The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab
N. Nikolov, D. K. Sing, J. Goyal +20
We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…
The CARMENES search for exoplanets around M dwarfs: High-resolution optical and near-infrared spectroscopy of 324 survey stars
A. Reiners, M. Zechmeister, J. A. Caballero +170
The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectr…
Effect of stellar flares on the upper atmospheres of HD 189733b and HD 209458b
J. M. Chadney, T. T. Koskinen, M. Galand +2
Stellar flares are a frequent occurrence on young low-mass stars around which many detected exoplanets orbit. Flares are energetic, impulsive events, and their impact on exoplaneta…
Far beyond the Sun: I. The beating magnetic heart in Horologium
Julián D. Alvarado-Gómez, Gaitee A. J. Hussain, Jeremy J. Drake +10
A former member of the Hyades cluster, Horologii ( Hor) is a planet-hosting Sun-like star which displays the shortest coronal activity cycle known to date (…
An ultrahot gas-giant exoplanet with a stratosphere
Thomas M. Evans, David K. Sing, Tiffany Kataria +24
Infrared radiation emitted from a planet contains information about the chemical composition and vertical temperature profile of its atmosphere. If upper layers are cooler than low…
