Investigating Possible Binarity for GJ 229B
Alex R. Howe, Avi M. Mandell, Michael W. McElwain
GJ 229B, the first type-T brown dwarf to be discovered, has presented a tension between comparisons with evolutionary models and the larger-than-expected mass and radius values der…
Variability in Proto-Planetary Nebulae: VIII. A New Sample of Southern Hemisphere Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +5
As part of our continuing study of light variability in proto-planetary nebulae (PPNe), we present the results from a long-term study of nine southern hemisphere objects. We have m…
Variability in Proto-Planetary Nebulae: VI. Multi-Telescope Light Curves Studies of Several Medium-Bright (V=13-15), Carbon-Rich Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +3
We present ten years of new photometric monitoring of the light variability of five evolved stars with strong mid-infrared emission from surrounding dust. Three are known carbon-ri…
Binary Central Stars of Planetary Nebulae Discovered Through Photometric Variability III: The Central Star of Abell 65
Todd C. Hillwig, David J. Frew, Melissa Louie +4
A growing number of close binary stars are being discovered among central stars of planetary nebulae. Recent and ongoing surveys are finding new systems and contributing to our kno…
