The Royal Astronomical Society of Canada and the Canadian Astronomical Society have established an award entitled The Plaskett Medal in recognition of the pivotal role played by John Stanley Plaskett in the establishment of astrophysical research in Canada. The award, consisting of a gold medal, is to be made annually to the Ph.D. graduate from a Canadian university who is judged to have submitted the most outstanding doctoral thesis in astronomy or astrophysics in the preceding two calendar years. The recipient is invited to address one or the other of the sponsoring Societies (at his or her choice) at their Annual Meeting, and to submit an invited article for the Journal of the Royal Astronomical Society of Canada (JRASC). The recipient will receive a $750 honorarium and all expenses to attend the meeting will be covered by that Society.
At most one candidate may be nominated by the head of his/her department from among the graduates of that university. The candidate need not have carried out his/her work in an astronomy or physics department.
Nominations for the 2013 award are closed.
For consideration for the 2014 award, the department head should send, in pdf format, the following materials to the chair of the awards committee:
- a letter of recommendation in support of the candidate/thesis (maximum three pages)
- a copy of the thesis
- a copy of the report from the outside examiner of the thesis
Copies of all materials should also be sent to the CASCA business office: casca at casca.ca. The deadline for submission is January 15, 2014. Note that if the thesis does not clearly indicate how much of its content represents the original work and ideas of the author, the department head should address this point in the letter. No other material should be submitted.
Note that the phrase “in the two preceding calendar years” in the eligibility rules makes it possible to re-nominate a candidate for whom an unsuccessful nomination was made in the preceding year. Because none of the documentation of previous nominations is retained for the use of the current selection committee, all re-nominations should be submitted with full documentation.
2013 Plaskett Medal
Dr. Hasegawa completed his doctoral studies in 2012 at McMaster University. His thesis, entitled “Planet Traps in Protoplanetary Disk and the Formation and Evolution of Planetary Systems”, was carried out under the supervision of Prof. Ralph Pudritz. This work explores in detail — from both a theoretical and computational perspective — the possibility that inhomogeneous structure in protostellar accretion disks can create ‘planet traps’ where major planets are built up primarily through the capture of rapidly migrating planetary cores, followed by the accretion of dense gas.
CASCA extends its congratulations to Dr. Hasegawa, who is currently an East Asian Core Observatories Association (EACOA) Fellow at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan.
