Nomination guidelines


The Robert J. Trumpler Award of the Astronomical Society of the Pacific is given each year to a recent recipient of the PhD degree in North America whose research is considered unusually important to astronomy.


To be considered for the Trumpler Award, a nominees Ph.D. must have been awarded within two years of the time of the nomination and most or all of the thesis must have been published in a recognized journal with an issue date prior to 15 February of the year in which the nomination is made. The nominee is eligible for two awards cycles the cycle for which the nomination was initially submitted and for the cycle following. Note that this is one year less than the length of eligibility for the other ASP awards.


Nominations are solicited from chairpersons of astronomy and physics departments in North America. The department chairperson should submit a resume or CV of the nominee, along with a letter of nomination (no more than two pages), supporting the selection and discussing the specific new research accomplishments in the PhD thesis, and the extent of independence exhibited by the nominee in the choice and execution of the thesis research. Appropriate journal citations to the scientific results must also be included. In addition to the nomination letter, we request that two independent letters of support (also no more than two pages each), be submitted for each nomination.

Only one nomination will be accepted from each institution per year, but under exceptional conditions two may be considered. Please contact the ASP to discuss the circumstances before submitting a second nomination.

Due Date

For a new nomination to be considered in any particular year, all nomination documents must be received by the Astronomical Society of the Pacific by March 1 of that year.

Contact the Awards team if you have any questions or need more information.


All nominations are reviewed by the Awards Committee appointed by the Board of Directors of the Astronomical Society of the Pacific. The Awards Committee recommends a recipient of the Award to the Board of Directors, which then makes the final selection. The Award recipient will be notified in the summer of the award year. If, in the opinion of the Awards Committee, none of the nominees is sufficiently outstanding, or if there are an insufficient number of nominations, the Award will not be given for the year in question.
