A new third planet and the dynamical architecture of the HD33142 planetary system

Trifon Trifonov, Anna Wollbold, Martin Kürster +24

Based on recently-taken and archival HARPS, FEROS and HIRES radial velocities (RVs), we present evidence for a new planet orbiting the first ascent red giant star HD33142 (with an…

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…

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…

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…
