30. Mapping hot massive stars in the Milky Way disc

Elenora Zari, John Bird

8/1/23, 11:00 AM

Hot massive stars dominate the stellar energy input to the interstellar medium, are laboratories for stellar evolution and multiplicity, and are tracers of recent star formation. One SDSS-V's core goals is to obtain multi-epoch BOSS spectra of over 300.000 OBA stars brighter than G=16 mag in the Galactic disc. From these spectra we will get estimates for masses, ages, metallicity,...

31. 101 X-rays & eROSITA: Introduction to Röntgen-Astronomy

Johannes Buchner

8/1/23, 11:25 AM

The principles of X-ray imaging-spectroscopy telescopes like eROSITA are presented, including basics of data collection and forward-folding modelling of spectra. Properties of eROSITA's first all-sky survey and its detected sources will be discussed.
