Planet-star interactions with precise transit timing. I. The refined orbital decay rate for WASP-12 b and initial constraints for HAT-P-23 b, KELT-1 b, KELT-16 b, WASP-33 b, and WASP-103 b
G. Maciejewski, M. Fernández, F. Aceituno +11
Theoretical calculations and some indirect observations show that massive exoplanets on tight orbits must decay due to tidal dissipation within their host stars. This orbital evolu…
Detection of Helium in the Atmosphere of the Exo-Neptune HAT-P-11b
Megan Mansfield, Jacob L. Bean, Antonija Oklopčić +11
The helium absorption triplet at a wavelength of 10,833 Å has been proposed as a way to probe the escaping atmospheres of exoplanets. Recently this feature was detected for the fir…
An optical transmission spectrum of the ultra-hot Jupiter WASP-33b. First indication of AlO in an exoplanet
C. von Essen, M. Mallonn, L. Welbanks +4
There has been increasing progress toward detailed characterization of exoplanetary atmospheres, in both observations and theoretical methods. Improvements in observational facilit…
Deciphering the atmosphere of HAT-P-12b: solving discrepant results
X. Alexoudi, M. Mallonn, C. von Essen +9
Two independent investigations of the atmosphere of the hot Jupiter HAT-P-12b by two different groups resulted in discrepant solutions. Using broad-band photometry from the ground,…
The TROY project: II. Multi-technique constraints on exotrojans in nine planetary systems
J. Lillo-Box, A. Leleu, H. Parviainen +10
Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the Solar System. Although planet-size co-orbitals do not exists in our planetary system, dyn…
Kepler Object of Interest Network II. Photodynamical modelling of Kepler-9 over 8 years of transit observations
J. Freudenthal, C. von Essen, S. Dreizler +14
The Kepler Object of Interest Network (KOINet) is a multi-site network of telescopes around the globe organised to follow up transiting planet candidate KOIs with large transit tim…
The CARMENES search for exoplanets around M dwarfs: A low-mass planet in the temperate zone of the nearby K2-18
Paula Sarkis, Thomas Henning, Martin Kürster +22
K2-18 is a nearby M2.5 dwarf, located at 34 pc and hosting a transiting planet which was first discovered by the {\it K2} mission and later confirmed with {\it Spitzer Space Telesc…
A Framework for Prioritizing the TESS Planetary Candidates Most Amenable to Atmospheric Characterization
Eliza M. -R. Kempton, Jacob L. Bean, Dana R. Louie +40
A key legacy of the recently launched TESS mission will be to provide the astronomical community with many of the best transiting exoplanet targets for atmospheric characterization…
GJ1214: Rotation period, starspots, and uncertainty on the optical slope of the transmission spectrum
M. Mallonn, E. Herrero, I. G. Juvan +6
Brightness inhomogeneities in the stellar photosphere (dark spots or bright regions) affect the measurements of the planetary transmission spectrum. To investigate the star spots o…
Kepler Object of Interest Network I. First results combining ground and space-based observations of Kepler systems with transit timing variations
C. von Essen, A. Ofir, S. Dreizler +35
During its four years of photometric observations, the Kepler space telescope detected thousands of exoplanets and exoplanet candidates. One of Kepler's greatest heritages has been…
KELT-21b: A Hot Jupiter Transiting the Rapidly-Rotating Metal-Poor Late-A Primary of a Likely Hierarchical Triple System
Marshall C. Johnson, Joseph E. Rodriguez, George Zhou +65
We present the discovery of KELT-21b, a hot Jupiter transiting the A8V star HD 332124. The planet has an orbital period of days and a radius of $…
