An Orbit for a Massive Wolf-Rayet Binary in the LMC: An Example of Binary Evolution
Breelyn Cocke, Philip Massey, Nidia I. Morrell +6
Wolf-Rayet (WR) stars are helium-burning, evolved massive stars which have had most of their hydrogen-rich outer layers removed either through stellar winds and/or binary stripping…
Where do stars explode in the ISM? -- The distribution of dense gas around evolved massive stars in M33
Sumit K. Sarbadhicary, Jordan Wagner, Eric W. Koch +27
The effect of supernovae (SNe) on star-formation in the interstellar medium (ISM) depends sensitively on where SNe explode with respect to ISM clouds. Observationally, SN ISM envir…
The Stellar Content of NGC~3603 Revisited: Is the IMF Top Heavy?
Philip Massey, Nidia I. Morrell, Kathryn F. Neugent +3
Studies of the resolved stellar populations of young massive clusters have shown that the slope of the initial mass function appears to be the same everywhere, with no dependence o…
A New Determination of the Mass of NGC 3603-A1: the Most Massive Binary Known?
Philip Massey, Sarah Bodansky, Laura R. Penny +2
The star NGC 3603-A1 has long been known to be a very massive binary, consisting of a pair of O2-3If*/WN5-6 stars, which show Wolf-Rayet-like emission due to their luminosities bei…
The Nature of a Recently Discovered Wolf-Rayet Binary: Archetype of Stripping?
Philip Massey, Kathryn F. Neugent, Nidia I. Morrell +2
LMCe055-1 was recently discovered in a survey for WRs in the Large Magellanic Cloud, and classified as a WN4/O4, a lower excitation version of the WN3/O3 class discovered as part o…
