Population Synthesis of Hot Subdwarfs: A Parameter Study
Drew Clausen, Richard A Wade, Ravi kumar Kopparapu +1
Binaries that contain a hot subdwarf (sdB) star and a main sequence companion may have interacted in the past. This binary population has historically helped determine our understa…
On the likelihood of non-terrestrial artifacts in the Solar System
Jacob Haqq-Misra, Ravi Kumar Kopparapu
Extraterrestrial technology may exist in the Solar System without our knowledge. This is because the vastness of space, combined with our limited searches to date, implies that any…
Search for Gravitational Waves from Low Mass Compact Binary Coalescence in LIGO's Sixth Science Run and Virgo's Science Runs 2 and 3
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +796
We report on a search for gravitational waves from coalescing compact binaries using LIGO and Virgo observations between July 7, 2009 and October 20, 2010. We searched for signals…
A photochemical model for the carbon-rich planet WASP-12b
Ravi kumar Kopparapu, James F. Kasting, Kevin J. Zahnle
The hot Jupiter WASP-12b is a heavily irradiated exoplanet in a short period orbit around a G0-star with twice the metallicity of the Sun. A recent thermochemical equilibrium analy…
All-sky Search for Periodic Gravitational Waves in the Full S5 LIGO Data
J. Abadie, B. P. Abbott, R. Abbott +794
We report on an all-sky search for periodic gravitational waves in the frequency band 50-800 Hz and with the frequency time derivative in the range of 0 through -6e-9 Hz/s. Such a…
Directional limits on persistent gravitational waves using LIGO S5 science data
J. Abadie, B. P. Abbott, R. Abbott +712
The gravitational-wave (GW) sky may include nearby pointlike sources as well as astrophysical and cosmological stochastic backgrounds. Since the relative strength and angular distr…
