RVSPY -- Radial Velocity Survey for Planets around Young Stars. Target characterization and high-cadence survey
O. Zakhozhay, R. Launhardt, A. Mueller +15
We introduce our Radial Velocity Survey for Planets around Young stars (RVSPY), characterise our target stars, and search for substellar companions at orbital separations smaller t…
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…
ISPY -- NaCo Imaging Survey for Planets around Young stars. CenteR: the impact of centering and frame selection
N. Godoy, J. Olofsson, A. Bayo +18
Abridged: Direct imaging has made significant progress over the past decade leading to the detection of several giant planets. Observing strategies and data rates vary from instrum…
ISPY -- NACO Imaging Survey for Planets around Young stars: Survey description and results from the first 2.5 years of observations
R. Launhardt, Th. Henning, A. Quirrenbach +21
The occurrence rate of long-period giant planets around young stars is highly uncertain since it is not only governed by the protoplanetary disc structure and planet formation proc…
Radial-velocity jitter of stars as a function of observational timescale and stellar age
Stefan S. Brems, Martin Kürster, Trifon Trifonov +2
Stars show various amounts of radial velocity (RV) jitter due to varying stellar activity levels. The typical amount of RV jitter as a function of stellar age and observational tim…
