Binary Evolution Leads to Two Populations of White Dwarf Companions
David S. Spiegel
Planets and other low-mass binary companions to stars face a variety of potential fates as their host stars move off the main sequence and grow to subgiants and giants. Stellar mas…
Jupiter will become a hot Jupiter: Consequences of Post-Main-Sequence Stellar Evolution on Gas Giant Planets
David S. Spiegel, Nikku Madhusudhan
When the Sun ascends the red giant branch (RGB), its luminosity will increase and all the planets will receive much greater irradiation than they do now. Jupiter, in particular, mi…
Optical and X-ray Transients from Planet-Star Mergers
Brian D. Metzger, Dimitrios Giannios, David S. Spiegel
We evaluate the prompt observational signatures of the merger between a massive close-in planet (a `hot Jupiter') and its host star, events with an estimated Galactic rate of ~0.1-…
Infrared Non-detection of Fomalhaut b -- Implications for the Planet Interpretation
Markus Janson, Joe Carson, David Lafreniere +3
The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion. In 2008,…
