Dynamical architecture of the HD 107148 system
Jan Eberhardt, Trifon Trifonov, Martin Kürster +15
We present an independent Doppler validation and dynamical orbital analysis of the two-planet system HD 107148, which was recently announced in Rosenthal et al. (2021). Our detaile…
Precise radial velocities of giant stars XV. Mysterious nearly periodic radial velocity variations in the eccentric binary Cygni
Paul Heeren, Sabine Reffert, Trifon Trifonov +10
Using the Hamilton Echelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 years, leadi…
K2-290: a warm Jupiter and a mini-Neptune in a triple-star system
M. Hjorth, A. B. Justesen, T. Hirano +41
We report the discovery of two transiting planets orbiting K2-290 (EPIC 249624646), a bright (V=11.11) late F-type star residing in a triple-star system. It was observed during Cam…
New HARPS and FEROS observations of GJ1046
Trifon Trifonov, Martin Kürster, Sabine Reffert +16
In this paper we present new precise Doppler data of GJ1046 taken between November 2005 and July 2018 with the HARPS and the FEROS high-resolution spectographs. In addition, we pro…
HD 89345: a bright oscillating star hosting a transiting warm Saturn-sized planet observed by K2
V. Van Eylen, F. Dai, S. Mathur +40
We report the discovery and characterization of HD 89345b (K2-234b; EPIC 248777106b), a Saturn-sized planet orbiting a slightly evolved star. HD 89345 is a bright star ( m…
Super-Earth of 8 Mearth in a 2.2-day orbit around the K5V star K2-216
C. M. Persson, M. Fridlund, O. Barragán +35
The KESPRINT consortium identified K2-216 as a planetary candidate host star in the K2 space mission Campaign 8 field with a transiting super-Earth. The planet has recently been va…
