Geometric albedos at short optical wavelengths for the hot Jupiters WASP-43b, WASP-103b, and TrES-3b

Matthias Mallonn, Enrique Herrero, Carolina von Essen

The largest and most close-in exoplanets would reflect enough star light to enable its ground-based photometric detection under the condition of a high to moderate albedo. We prese…

Probing the atmosphere of HD189733b with the Na I and K I lines

E. Keles, D. Kitzmann, M. Mallonn +12

High spectral resolution transmission spectroscopy is a powerful tool to characterize exoplanet atmospheres. Especially for hot Jupiters, this technique is highly relevant, due to…

Role of the impact parameter in exoplanet transmission spectroscopy

X. Alexoudi, M. Mallonn, E. Keles +3

Transmission spectroscopy is a promising tool for the atmospheric characterization of transiting exoplanets. Because the planetary signal is faint, discrepancies have been reported…

Asteroseismology of the Multiplanet System K2-93

Mikkel N. Lund, Emil Knudstrup, Victor Silva Aguirre +14

We revisit the analysis of the bright multiplanet system K2-93, discovered with data taken by the K2 mission. This system contains five identified planets ranging in size from sub-…

Gaia Data Release 2. Summary of the contents and survey properties

Gaia Collaboration, A. G. A. Brown, A. Vallenari +4

We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…

Gaia Data Release 2: Properties and validation of the radial velocities

D. Katz, P. Sartoretti, M. Cropper +51

For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…

OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary

Y. -H. Ryu, J. C. Yee, A. Udalski +106

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…
