Abigail Frost, KU LeuvenProbing massive stars from young to old with optical/IR interferometryMassive stars, those at least eight times the mass of our Sun, are very influential sources, affect not only their local environments but also their galaxies as a whole. Their luminosities dominate in spatially unresolved galaxies, and their winds are powerful to the point that they affect the topology of galactic superwinds (e.g. Leitherer 1994). Massive stars are also the originators of many exotic phenomena, from core-collapse supernovae (which enrich to interstellar medium) to neutron stars, black holes and their associated gravitational waves. Gravitational waves in particular are a result of the multiplicity of massive stars (Abbot et al. 2016) which has the potential to completely alter the evolutionary pathway of the involved stars if the stars interact. In this talk I will discuss some of the interesting massive multiple systems (including potential merger systems and stars stripped by interaction in binary systems) and how I probe the massive star formation process with IR interferometry.
FLASH Talks are scientific talks for the staff at NOIRLab and the University of Arizona's Steward Observatory.
If you or a collaborator are interested in presenting at FLASH please get in touch. All FLASH talks are virtual for the foreseeable future, so feel free to suggest speakers from outside of Tucson!
