Join the massive stars group in Tel Aviv!
I am currently hiring at all levels: MSc, PhD, postdocs!
What you gain...
-
Work with advanced analysis techniques of spectroscopy and interferometry
-
Work in big international collaborations
-
Use the most advanced observatories (the Very Large Telescope, Hubble Space Telescope, James Webb Space Telescope…)
-
Exclusive access to propriety data
-
Work with advanced models of radiative transfer and analysis algorithms
-
Projects available both on either model development or observational astrophysics
-
Access to affordable accommodation in the vibrant city of Tel Aviv
Work on diverse projects...
Classical Wolf-Rayet (WR) stars represent the final evolutionary stages of stars at the upper mass end, and are the putative immediate progenitors of black holes. Available projects include:
-
The carbon-rich WR stars (WC) in the Large Magellanic Cloud with HST + VLT
-
The nitrogen-rich WR stars (WN) in the Large Magellanic Cloud with 4MOST/Vista
-
Analysis of Galactic WR binaries
campaign
The "Binarity at LOw Metallicity" (BLOeM) campaign is an unprecedented spectroscopic monitoring survey of ~1000 massive stars in the Small Magellanic Cloud with ESO's Very Large Telescope. Possible projects include:
-
Derivation of binary fractions of various subsamples
-
Derivation of orbits of various subsamples
-
Spectral analysis of various subsamples
-
Black-hole hunt
Oe/Be stars are rapidly rotating stars with disks, thought to represent binaries which have previously interacted. Possible projects include:
-
Interferometry of a Galactic sample of Oe/Be stars
-
Spectroscopy of a sample of Oe/Be stars & binaries
The Potsdam Wolf-Rayet (PoWR) code is a widely used state-of-the-art model atmosphere code designed for massive stars with expanding atmospheres.
If you are inclined to theory and programming, developing new modules in the PoWR code (e.g., time-dependent radiative transfer) is a viable option.
