FUSE Observations of the Post-AGB Star ZNG 1 in the Globular Cluster M5 (NGC 5904)
W. V. Dixon, T. M. Brown, W. B. Landsman
We have observed the hot post-AGB star ZNG 1 in the globular cluster M5 with the Far Ultraviolet Spectroscopic Explorer (FUSE). From the resulting spectrum, we derive an effective…
A New Formation Mechanism for the Hottest Horizontal-Branch Stars
Allen V. Sweigart, Thomas M. Brown, Thierry Lanz +2
Stars with very large mass loss on the red-giant branch can undergo the helium flash while descending the white-dwarf cooling curve. Under these conditions the flash convection zon…
100 Times Faster and 3 Times Sharper: Background-Dominated Observations of Stellar Populations with an 8-meter Optical-UV Space Telescope
Thomas M. Brown
An 8 m successor to the Hubble Space Telescope (HST) would make incredible gains in the study of stellar populations, especially in the Local Group. If diffraction-limited at 0.5 m…
Using M32 to Study Rapid Phases of Stellar Evolution
Thomas M. Brown, Henry C. Ferguson, Allen V. Sweigart +2
The compact elliptical galaxy M32 offers a unique testing ground for theories of stellar evolution. Because of its proximity, solar-blind UV observations can resolve the hot evolve…
