The fellowship provides an opportunity for recent doctoral scientists to develop innovative instrumentation or to conduct novel theoretical and observational research in planetary astronomy. Planetary astronomy brings together research efforts of two fields—planetary science and astronomy—to characterize planetary systems. The fellowship supports postdoctoral fellows to advance our fundamental understanding of exoplanets, solar system science, planet formation and evolution, planetary atmospheres, protoplanetary disks, or other closely related topics.

The fellowship recognizes early-career investigators of significant potential and provides them with the opportunity to conduct independent research. Each recipient will receive a three-year grant of up to $415,000 to cover salary, benefits, highly-flexible discretionary spending (e.g., travel, family care, moving expenses, research equipment, personal computers, etc.), and indirect costs.  Awarded postdoctoral fellows are expected to carry out a strong, coherent research program in planetary astronomy.

The Foundation anticipates awarding six to eight fellowships this year, based on the quality of submissions. The Heising-Simons Foundation is committed to diversity, equity, and inclusion . Thus, we particularly welcome applications from individuals who belong to groups that have been historically underrepresented in planetary sciences and astronomy such as women, persons with disabilities, racial and ethnic minorities, persons of minority sexual orientation or gender identity, and others who may contribute to diversification of the field.

The 2022-2023 Fellowship cycle is now closed.

Eligibility Criteria

  • Applicants may come from any academic institution or research lab, both nationally and internationally.
  • Applicants are not required to have US citizenship; however, all visa and work permit paperwork is the responsibility of the fellow and host institution.
  • Applicants must have received a doctoral degree in astronomy, physics, earth and planetary sciences, chemistry, mathematics, engineering, or a related discipline. Doctoral degrees must be awarded after August 31, 2012 and before August 31, 2022.

51 Pegasi b Fellowship research must be pursued at one of the following participating institutions. If you have any questions about research collaborations, faculty mentors, resources at these host institutions, etc., please contact the people listed below:

Review Criteria

In preparing your research proposal and supporting materials, please consider that fellowship applications will be evaluated based on the following six equally-weighted criteria:

  • Research significance to the field:  Does the research address an important problem or a critical barrier in planetary astronomy? Will meeting the science objectives have broad, long-lasting, cross-cutting, or catalytic impacts on the field?
  • Research innovation:  Is the proposed research original and innovative?  Does the proposed research challenge existing research approaches and ideas? Does the project develop or employ novel concepts, approaches, tools, or technologies?
  • Research approach:  Is the overall strategy well-reasoned and appropriate to accomplishing the project goals? Are the resource requirements and proposed timelines reasonable? Are project risks recognized and addressed?
  • Applicant qualification: Does the applicant have the necessary education and training to carry out the project? Does the applicant have relevant research experience? Has the applicant demonstrated the ability to lead and complete projects?
  • Suitability of host institution(s): Does a proposed host institution have the necessary resources and faculty to support the postdoctoral fellow both scientifically and professionally?
  • Diversity, Equity, and Inclusion (DEI) statement:  Does the applicant have demonstrated personal experiences, professional skills, and/or a willingness to engage in and lead activities that will advance DEI in the field, particularly with respect to groups which have been historically and consistently underrepresented in the field? Does the applicant offer thoughtful and specific/concrete ideas regarding DEI in the field?

  • Science research proposal describing the work you want to perform as a 51 Pegasi b Fellow (up to three pages)
  • Brief Diversity, Equity, and Inclusion (DEI) statement detailing personal experiences, professional skills, and/or willingness to engage in activities that will advance DEI in the field

Application FAQ

The funding for your fellowship is routed through your host institution. Temporary working arrangements at external sites (e.g. observatories, national labs, etc.) are permissible if they support your proposed research and are endorsed by your faculty mentor and institution.

The 51 Pegasi b Fellowship has forged a partnership with your host institution to ensure a rich experience by establishing access to faculty mentors and other resources to excel in your research endeavors. Therefore, we highly encourage you to stay at your host institution during the duration of your fellowship term. Should a fellow require a location change, they should notify the Foundation immediately. Each request will be assessed and approved on a case by case basis.

No, the three-page limit does not include references, figures, and tables. An additional 2 pages may be included for references, figures, and tables for a total of 5 pages.

Yes, following the review and final selection process, the excel budget template and guidelines will be shared with the 51 Pegasi b recipient. The budget must be reviewed and endorsed by the host institution’s office of sponsored projects

No, you may only submit two letters of recommendation. These letters must be provided by the candidate’s Ph.D. advisor, a senior collaborator, or a scientific mentor.

Changes to your submitted application can only be made during the open period of the online application platform.

The deadline cannot be extended. There are no exceptions.

All selected applicants will be notified in February.
