Galaxy UV Legacy Project: Survey Description and First Insights Into NGC 4449 Recent History of Star Formation
E. Sabbi, B. Meena, P. Zeidler +18
The Galaxy UV Legacy Project (GULP) is a Cycle 28 Treasury program with the Hubble Space Telescope (HST) designed to characterize resolved massive stars, OB associations, and young…
Isolated massive star candidates in NGC 4242 with GULP
Pietro Facchini, Eva K. Grebel, Anna Pasquali +16
There is considerable debate on how massive stars form, including whether a high-mass star must always form with a population of low-mass stars or whether it ca…
New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling
Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9
We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…
GULP II: Hierarchical Distribution and Evolution of Young Stellar Structures in NGC 4449
Beena Meena, Elena Sabbi, Peter Zeidler +15
We investigate the hierarchical distribution and evolution of young stellar structures in the dwarf starburst galaxy NGC 4449 using data from the GULP survey. By analyzing the spat…
BPASS stellar evolution models incorporating -enhanced composition -- I. Single star models from 0.1 to 316 M
Conor M Byrne, Jan J Eldridge, Elizabeth R Stanway
Stellar evolution modelling is fundamental to many areas of astrophysics including stellar populations in both nearby and distant galaxies. It is heavily influenced by chemical com…
