The Leiden/ESA Astrophysics Program for Summer Students (LEAPS) 2017

Update: 29, November 2016

Please check back mid-December for the list of projects.

LEAPS is an opportunity for students with an interest in astronomy and astrophysics to perform a 10-12 week summer research project in collaboration with a research scientist from Leiden Observatory or ESA. The program is open to all students not currently engaged in a Ph.D. program, although most past participants have been senior-undergraduate or masters' students who are enthusiastic about research in astrophysics.

Students will be selected for the program based on their academic achievements and research potential, and will be matched to staff projects based on what they indicate their scientific interests to be. Research at Leiden Observatory and ESA takes place on a diverse array of topics (see below), and student projects will likely consist of anything from the analysis of data from world-class telescopes, to large computer simulations, to hands-on work in the astrochemistry laboratories.

Projects will begin in June 2017 and end before end-August 2017.

Leiden Observatory

Leiden Observatory is a world-class institute for research in astronomy and astrophysics based in the Netherlands, approximately 35km from Amsterdam. The atmosphere at the observatory is dynamic, with approximately 100 faculty/research scientists and 70 graduate students engaged in astrophysical research on a wide range of topics. Major fields of interest include extrasolar planets, star formation, cosmology, galaxy formation, instrumentation, and astrochemistry. Multiple research projects will likely be available within these fields.


European Space Research and Technology Centre (ESTEC/ESA)

ESTEC is the main technical centre for the European Space Agency (ESA), responsible for spacecraft integration. ESA develops and manages many types of space missions, from exploration, telecommunications, to earth and space science. The Research and Scientific Support Department at ESTEC consists of approximately 40 staff scientists, with research interests ranging from the geology of planets in our solar system, to plasma physics in the magnetosphere of the Earth, space weather, to observational astronomy with ESA's space missions such as Planck, Herschel, GAIA and EUCLID. Due to tight security requirements for entry to the ESTEC complex, students who work in collaboration with the ESTEC Research Fellows will be based primarily at Leiden Observatory and their advisor will meet with them on a regular basis.

Travel, Housing and Stipend

Students accepted into the LEAPS program will be provided with travel costs to/from Leiden. We will also provide housing accommodations near the observatory, as well as a modest stipend to help with living costs during the internship. Leiden is a small, picturesque university town located between the major cities of Amsterdam and The Hague. Summer is a beautiful time of year to be in Leiden, and we encourage LEAPS students to socialize and use their free time to enjoy the numerous summertime activities available in Holland. English is widely spoken throughout the Netherlands and international students should find it easy to live in the Leiden area. We are planning several field trips for LEAPS students including visits to the ESTEC complex where many ESA satellites are being built, and potentially to the LOFAR radio array, the world's largest low-frequency radio telescope.

How to Apply

Under construction more info soon, stay tune and check back in mid-December

The program is open to all international students provided they are not currently enrolled in a Ph.D. program. ESA projects are only available for students from ESA member or affiliate states (Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, The Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland, the United Kingdom and Canada). Students from Cyprus, Estonia, Hungary, Latvia and Slovenia (affilliate members) can also apply for ESA projects. The working language of the observatory is English, and students should be sufficiently proficient in English to perform a research project.


Research Projects, Categories and Supervisors


The research projects proposed for the LEAPS Program 2017 are currently being collected and the list will be updated shortly. Under construction more info soon, stay tune and check back in mid-December


Please note that the ESA projects are only available for students from ESA member or affiliate states (Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, The Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland, the United Kingdom, and Canada). Students from Cyprus, Estonia, Hungary, Latvia and Slovenia (affilliate members) can also apply for ESA projects.

Previous LEAPS Successes


LEAPS 2015 was a great success! Twenty-two students from four continents spent their summer in Leiden doing astrophysics research.

  • Joshua Borrow (with supervisor Pedro Russo) published a paper on astro-ph entitled "A Blueprint for Public Engagement Appraisal: Supporting Research Careers."
  • Lukasz Tychoniec (supervised by John Tobin) presented his research at the Polish Astronomical Society Summit, and his research already contributed to one published paper and he is preparing a paper on the full results.
  • Tessa Wilkinson (supervised by Anna-Lea Lesage) presented her research at the 2016 American Astronomical Society meeting.
  • Jeremy Dietrich (supervised by Christian Ginksi) submitted a paper to MNRAS "Archival VLT/NaCo multiplicity investigation of exoplanet host stars".
  • Maria Vincenzi (supervised by Carlo Manara) presented a poster at the workshop: "The accretion/outflow connection in YSOs" at ESTEC in October and a paper is in preparation.
  • Hope Boyce (supervised by Nora Lutzgendorf) presented a poster at the Canadian Conference for Undergraduate Women in Physics and a paper is in preparation.

The 2013, and 2014 groups of LEAPS students also performed very well and the first scientific publications are out!

  • Ryosuke Goto and his advisor Sean McGee published a paper on galaxy formation in the Monthly Notices of the Royal Astronomical Society on his LEAPS project; "The stellar mass function and efficiency of galaxy formation with a varying initial mass function". See here.
  • Steffi Yen and her advisor, Adam Muzzin, presented a poster at the American Astronomical Society (AAS) winter meeting in Washington DC, "Searching for the Most Distant Galaxy Clusters". See here.
  • Fiona Thiessen and her advisor Sebastien Besse submitted a paper on Lunar surface composition and lava flows (figure below).
  • Conny Weber worked with Agnes Kospal on infrared variability of young stars in Chamaeleon which featured on a poster at the "The Universe Explored by Herschel" conference in Noordwijk (conference website). See the poster here.
  • Hannah Harris, a 2014 LEAPS student, and her advisor Pedro Russo published a paper in the Space Policy Journal, "The Influence of Social Movements on Space Astronomy Policy." See here.
  • Saul Kohn (now a PhD student at UPenn) and his advisor David Sobral published a paper in Monthly Notices of the Royal Astronomical Society on his LEAPS project: "The most luminous Halpha emitters at z~0.8-2.23 from HiZELS". See here (link here).
  • LEAPS student Michael Hammer (from Cornell University) and his adviser Lucie Jilkova studied close stellar flybys that lead some stars to lose parts of their circumstellar discs. Using simulations in the AMUSE framework (www.amusecode.org), they showed that if the two stars approach each other close enough, part of the disc lost from one star can be transferred to the other one. These close encounters can happen shortly after stars form when many stars are clustered together. They further showed that even our Solar System might have experienced such an interaction and stolen some material, which is now orbiting in its outer parts, from another star. Michael presented a poster on the results of his LEAPS project on the 225th AAS meeting. The project eventually resulted to publication in an international refereed journal, which led to several press releases, for example: New Scientist, Scientific American, Universe Today.

Numbers indicate the basalt units mapped in this work. Large and spectrally bright craters are mapped separately in grey and were excluded from the basalt units. The surrounding highlands and kipuckas inside the Imbrium basin are also shown in grey. Dark strips correspond to portion of the lunar surface not observed with M3 using OP1B.
