The CARMENES search for exoplanets around M dwarfs: Stable radial-velocity variations at the rotation period of AD~Leonis -- A test case study of current limitations to treating stellar activity
D. Kossakowski, M. Kürster, Th. Henning +34
Context: A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. In fact, the existence of a p…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
CARMENES input catalog of M dwarfs VI. A time-resolved Ca II H&K catalog from archival data
V. Perdelwitz, M. Mittag, L. Tal-Or +15
Radial-velocity (RV) jitter caused by stellar magnetic activity is an important factor in state-of-the-art exoplanet discovery surveys such as CARMENES. Stellar rotation, along wit…
The CARMENES search for exoplanets around M dwarfs. Two terrestrial planets orbiting G 264-012 and one terrestrial planet orbiting Gl 393
P. J. Amado, F. F. Bauer, C. Rodríguez López +51
We report the discovery of two planetary systems, namely G 264-012, an M4.0 dwarf with two terrestrial planets ( M and $M_{\rm c…
Hybrid star HD 81817 accompanied by brown dwarf or substellar companion
Tae-Yang Bang, Byeong-Cheol Lee, V. Perdelwitz +4
HD 81817 is known as a hybrid star. Hybrid stars have both cool stellar wind properties and Ultraviolet (UV) or even X-ray emission features of highly ionized atoms in their spectr…
The first Doppler imaging of the active binary prototype RS Canum Venaticorum
Yue Xiang, Shenghong Gu, U. Wolter +6
We present the first Doppler images of the prototypical active binary star RS CVn, derived from high-resolution spectra observed in 2004, 2016 and 2017, using three different teles…
