Title |
Planetary Remnants Around White Dwarfs | |||||
| Coauthors | Mukremin Kilic, Sara Barber, Claudia Belardi | |||||||
|
Abstract |
Planets around white dwarfs may be common, and they may provide our best chance to detect bio-markers on a transiting exoplanet, thanks to the diminished contrast ratio between the white dwarf and its planets. Here we present results from a recent Spitzer Space Telescope survey of bright white dwarfs, and compare the frequency of remnant planetary systems around white dwarfs with planet formation models. We also present the first results from a minute-cadence transit survey for planets in the white dwarf habitable zone. |

Title |
The first pulsar + pulsating white dwarf binary | |||||
| Coauthors | ||||||||
|
Abstract |
Our targeted survey of extremely low mass white dwarfs has discovered a significant number of compact binaries in the last 5 years. Some of these systems are strong gravitational wave sources and potential progenitors of under-luminous or type Ia supernovae and AM CVn systems. I will present the most recent highlights from the ELM Survey including the limits on potential neutron star companions, the discovery of a new 20-min orbital period binary system, and the first ever discovery of a millisecond pulsar + pulsating white dwarf binary. |
