Habitable Zones Around Main-Sequence Stars: New Estimates
- R. Kopparapu, R. Ramirez, R. Deshpande
- Physics, Geology
- 28 January 2013
Identifying terrestrial planets in the habitable zones (HZs) of other stars is one of the primary goals of ongoing radial velocity (RV) and transit exoplanet surveys and proposed future space…
Predictions for the rates of compact binary coalescences observable by ground-based gravitational-wave detectors
- L. S. Collaboration, Virgo Collaboration J. Abadie, K. Belczynski
- Physics
- 12 March 2010
We present an up-to-date, comprehensive summary of the rates for all types of compact binary coalescence sources detectable by the initial and advanced versions of the ground-based gravitational-wave…
HABITABLE ZONES AROUND MAIN-SEQUENCE STARS: DEPENDENCE ON PLANETARY MASS
- R. Kopparapu, R. Ramirez, J. Schottelkotte, J. Kasting, S. Domagal‐Goldman, V. Eymet
- Physics, Geology
- 21 April 2014
The ongoing discoveries of extra-solar planets are unveiling a wide range of terrestrial mass (size) planets around their host stars. In this Letter, we present estimates of habitable zones (HZs)…
A REVISED ESTIMATE OF THE OCCURRENCE RATE OF TERRESTRIAL PLANETS IN THE HABITABLE ZONES AROUND KEPLER M-DWARFS
- R. Kopparapu
- Physics, Geology
- 11 March 2013
Because of their large numbers, low-mass stars may be the most abundant planet hosts in our Galaxy. Furthermore, terrestrial planets in the habitable zones (HZs) around M-dwarfs can potentially be…
Host Galaxies Catalog Used in LIGO Searches for Compact Binary Coalescence Events
- R. Kopparapu, C. Hanna, S. Fairhurst
- Physics
- 9 June 2007
An up-to-date catalog of nearby galaxies considered to be hosts of binary compact objects is provided, with complete information about sky position, distance, extinction-corrected blue luminosity,…
Warming early Mars with CO 2 and H 2
- R. Ramirez, R. Kopparapu, M. Zugger, T. Robinson, R. Freedman, J. Kasting
- Physics, Geology
- 26 May 2014
Ancient valleys suggest a warm early Mars where liquid water flowed, but a greenhouse effect strong enough to offset a dim early Sun has been difficult to explain. Climate simulations suggest that…
ERRATUM: “HABITABLE ZONES AROUND MAIN-SEQUENCE STARS: NEW ESTIMATES” (2013, ApJ, 765, 131)
- R. Kopparapu, R. Ramirez, R. Deshpande
- Physics, Geology
- 24 May 2013
Identifying terrestrial planets in the habitable zones (HZs) of other stars is one of the primary goals of ongoing radial velocity (RV) and transit exoplanet surveys and proposed future space…
A PHOTOCHEMICAL MODEL FOR THE CARBON-RICH PLANET WASP-12b
- R. Kopparapu, J. Kasting, K. Zahnle
- Geology, Physics
- 12 October 2011
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 analysis based on…
The inner edge of the habitable zone for synchronously rotating planets around low-mass stars using general circulation models
- R. Kopparapu, E. Wolf, S. Mahadevan
- Physics, Geology
- 16 February 2016
Terrestrial planets at the inner edge of the habitable zone of late-K and M-dwarf stars are expected to be in synchronous rotation, as a consequence of strong tidal interactions with their host…
An upper limit on the stochastic gravitational-wave background of cosmological origin
- B. Abbott, R. Abbott, J. Rollins
- PhysicsNature
- 20 August 2009
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmological origin. It should…
