Abstract:
Most current radial velocity planet search programs have concentrated
on stars of one solar mass. Our knowledge on the frequency of giant
planets and brown dwarf companions to more massive stars is thus
rather limited. In the case of solar-like stars, the frequency of
short-period brown dwarf companions and very massive planets seems to
be low. Aims. Here we present evidence for a substellar companion to
30 Ari B, an F-star of 1.16±0.04M☉ that is a member of a
hierarchical triple system.
The companion was detected by means of precise radial velocity
measurements using the 2-m Alfred-Jensch telescope and its echelle
spectrograph. An iodine absorption cell provided the wavelength
reference for precise stellar radial velocity measurements.
Description:
The table contains the relative radial velocity measurements of 30 Ari
B with the 2-m Alfred-Jensch telescope at the Thueringer
Landessternwarte Tautenburg.
