Astrophysics of stellar-merger remnants with interferometric techniques | Closing date: 2021-07-31 Contact: Tomasz Kaminski |
We invite applications for a PhD position in astrophysics at the Nicolaus Copernicus Astronomical Center (CAMK) of the Polish Academy of Sciences. The scholarships will be executed in Department for Astrophysics which is a CAMK branch located in the center of the beautiful old town of Torun, Poland. | ▸ more | The PhD candidate will investigate physical and chemical structure of remnants of red nova eruptions. The remnants of red novae are thought to be sites of recent stellar mergers. Examples include objects V838 Mon and V1309 Sco. The main science aims include investigating physical processes that govern the common-envelope phase, stellar-collisions, mass loss in binaries, and binary interaction in eruptive systems. The PhD candidates will work mainly with interferometric data acquired at centimeter and submillimeter wavelengths with ALMA, SMA, and JVLA. Most of the interferometric observations have been collected or are scheduled for execution in the near future. The Ph.D. candidate will be expected to develop optimal interferometric imaging techniques and investigate the physical structure of the remnants using existing tools for solving the radiative-transfer problem. The Ph.D. candidate will be also expected to secure multi-wavelength auxiliary data at other facilities, such as SOFIA and VLT. Frequent training trips to ESO (Garching & Santiago) and interferometry schools/workshops are foreseen during the course of the Ph.D.
To learn more on the science project, see here or contact dr T. Kaminski at tomkam @ ncac.torun.pl.
A prior experience with interferometric data or molecular spectroscopy are welcome but are not required. Proficiency in python programming will be considered as an asset. Applicants should hold (or expect to obtain before the start of the position) a university degree (master or equivalent) in the field of astrophysics, astronomy, or physics.
Funding: This offer is accompanied by a scholarship competition from the National Science Center SONATA BIS project, number 2018/30/E/ST9/00398, entitled "Stellar mergers: causes and aftermath of stellar collisions investigated with interferometric methods" led by dr Tomasz Kaminski. Scholarship in the total amount of 4500 PLN/month, gross, is available for 3 years.
Location: Torun, Poland
Supervisor: Dr Tomasz Kaminski (contact: tomkam @ ncac.torun.pl)
