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…

A transiting, temperate mini-Neptune orbiting the M dwarf TOI-1759 unveiled by TESS

Néstor Espinoza, Enric Pallé, Jonas Kemmer +66

We report the discovery and characterization of TOI-1759~b, a temperate (400 K) sub-Neptune-sized exoplanet orbiting the M~dwarf TOI-1759 (TIC 408636441). TOI-1759 b was observed b…

Discovery and mass measurement of the hot, transiting, Earth-sized planet GJ 3929 b

J. Kemmer, S. Dreizler, D. Kossakowski +64

We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180--18, TOI-2013). Joint modelling of photometric observations fro…

A nearby transiting rocky exoplanet that is suitable for atmospheric investigation

T. Trifonov, J. A. Caballero, J. C. Morales +66

Spectroscopy of transiting exoplanets can be used to investigate their atmospheric properties and habitability. Combining radial velocity (RV) and transit data provides additional…

Auto-correlation functions of astrophysical processes, and their relation to Gaussian processes; Application to radial velocities of different starspot configurations

Manuel Perger, Guillem Anglada-Escudé, Ignasi Ribas +3

Accounting for the effects of stellar magnetic phenomena is indispensable to fully exploit radial velocities (RVs). Correlated time variations are often mitigated by Gaussian proce…

Discovery of a hot, transiting, Earth-sized planet and a second temperate, non-transiting planet around the M4 dwarf GJ 3473 (TOI-488)

J. Kemmer, S. Stock, D. Kossakowski +93

We present the confirmation and characterisation of GJ 3473 b (G 50--16, TOI-488.01), a hot Earth-sized planet orbiting an M4 dwarf star, whose transiting signal ($P=1.1980035\pm0.…
