Manos Zapartas awarded the Swiss Government Excellence Prize Fellowship

15 May
Dr. E. (Manos) Zapartas

Manos Zapartas is a very recent BinCosmos PhD graduate, who only left our group a few months ago for Geneva observatory. We are very excited to share that he has been awarded the competitive Swiss Government Excellence Fellowship. This allows him to pursue his research on the final fate of massive binary stars. He will do so as a member of the group of dr. Tassos Fragos, who recently joined Geneva Observatories last year as an assistant professor.

Postdoc Athira Menon wins National Famelab competition

15 May

Group member Athira Menon, postdoc in the BinCosmos group, won the Dutch final of FameLab on 9 May. FameLab is a pitch competition for young researchers, in which they have only three minutes to explain their research to the general public.  By winning the national final, she won a trip to Cheltenham, England, to compete at the annual Cheltenham Science Festival (June 4-9) against 24 other FameLab winners from around the world.

Elected as member of the Dutch Young Academy of Sciences

24 Mar

De Mink is one of the ten new members of the Dutch National Young academy of sciences, installed March 21, 2019. The Academy unites Dutch talented scientists across all academic disciplines that obtained their Ph.D. less than ten years ago. In addition to having an outstanding track record, they share a strong interest in science policy and science communication. Membership is for five years. Read about the profiles of the ten new members here.

Preprint: Impact of stripped stars on integrated spectra

11 Jan

Ylva Götberg’s third thesis paper has been submitted to A&A. In this paper, we present predictions for the integrated spectra of stellar populations including the hard ionizing photons expected from hot stars that have lost their envelope through interaction with a binary companion. The SED’s will be made available through the STARBURST99 portal. Find a preview here.

Preprint: Pulsational pair-instability supernovae in very close binaries

4 Jan

Anticipating new gravitational wave detections of heavy binary black holes, Pablo Marchant (CIERA) together with Bincosmos group members Mathieu Renzo and Rob Farmer’s explore the effects of pulsations experienced by the most massive stars. Find a preview here.

Gaia & HST astrometry of a very massive ˜150 M⊙ candidate runaway star

1 Jan

A 150 Msun candidate runaway star.

Mathieu Renzo’s investigation of what is probably the most massive runaway star currently known. Using Gaia and Hubble Space Telescope data he tries to determine the origin of this extreme star, which has likely been ejected by the very young star cluster R136. The cluster is famous for harboring several of these monster stars as shown in earlier work. Now published in MNRAS.
