Warm Spitzer Photometry of XO-4b, HAT-P-6b and HAT-P-8b
Kamen O. Todorov, Drake Deming, Heather A. Knutson +11
We have analyzed Warm Spitzer/IRAC observations of the secondary eclipses of three planets, XO-4b, HAT-P-6b and HAT-P-8b. We measure secondary eclipse amplitudes at 3.6μm and 4.5μm…
Combining Kepler and HARPS Occurrence Rates to Infer the Period-Mass-Radius Distribution of Super-Earths/Sub-Neptunes
A. Wolfgang, G. Laughlin
The ongoing High Accuracy Radial velocity Planet Search (HARPS) has found that 30-50% of GK dwarfs in the solar neighborhood host planets with sub-Neptune masses in orbits of P < 5…
Kepler Exoplanet Candidate Host Stars are Preferentially Metal Rich
Kevin C. Schlaufman, Gregory Laughlin
We find that Kepler exoplanet candidate (EC) host stars are preferentially metal-rich, including the low-mass stellar hosts of small-radius ECs. The last observation confirms a ten…
A Spitzer Transmission Spectrum for the Exoplanet GJ 436b, Evidence for Stellar Variability, and Constraints on Dayside Flux Variations
Heather A. Knutson, Nikku Madhusudhan, Nicolas B. Cowan +10
In this paper we describe a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 micron bands using t…
Improved Orbital Parameters and Transit Monitoring for HD 156846b
Stephen R. Kane, Andrew W. Howard, Genady Pilyavsky +10
HD 156846b is a Jovian planet in a highly eccentric orbit (e = 0.85) with a period of 359.55 days. The pericenter passage at a distance of 0.16 AU is nearly aligned to our line of…
Resolving the Sin(I) degeneracy in Low-Mass Multi-Planet Systems
Konstantin Batygin, Gregory Laughlin
Long-term orbital evolution of multi-planet systems under tidal dissipation often converges to a stationary state, known as the tidal fixed point. The fixed point is characterized…
