Multiperiodicity, modulations and flip-flops in variable star light curves III. Carrier fit analysis of LQ Hya photometry for 1982-2014
Nigul Olspert, Maarit J. Käpylä, Jaan Pelt +4
We study LQ Hya photometry for 1982-2014 with the carrier fit (CF) -method and compare our results to earlier photometric analysis and recent Doppler imaging maps. We first utilize…
HST hot-Jupiter transmission spectral survey: Haze in the atmosphere of WASP-6b
N. Nikolov, D. K. Sing, A. S. Burrows +14
We report Hubble Space Telescope (HST) optical to near-infrared transmission spectroscopy of the hot Jupiter WASP-6b, measured with the Space Telescope Imaging Spectrograph (STIS)…
HST hot-Jupiter transmission spectral survey: detection of potassium in WASP-31b along with a cloud deck and Rayleigh scattering
D. K. Sing, H. R. Wakeford, A. P. Showman +15
We present Hubble Space Telescope optical and near-IR transmission spectra of the transiting hot-Jupiter WASP-31b. The spectrum covers 0.3-1.7 m at a resolution 70, which…
A Precise Water Abundance Measurement for the Hot Jupiter WASP-43b
Laura Kreidberg, Jacob L. Bean, Jean-Michel Désert +13
The water abundance in a planetary atmosphere provides a key constraint on the planet's primordial origins because water ice is expected to play an important role in the core accre…
Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy
Kevin B. Stevenson, Jean-Michel Desert, Michael R. Line +13
Exoplanets that orbit close to their host stars are much more highly irradiated than their Solar System counterparts. Understanding the thermal structures and appearances of these…
The NASA-UC-UH Eta-Earth Program: IV. A Low-mass Planet Orbiting an M Dwarf 3.6 PC from Earth
Andrew W. Howard, Geoffrey W. Marcy, Debra A. Fischer +8
We report the discovery of a low-mass planet orbiting Gl 15 A based on radial velocities from the Eta-Earth Survey using HIRES at Keck Observatory. Gl 15 Ab is a planet with minimu…
