Abstract:
We present the results of our second radial velocity (RV) monitoring
campaign, carried out with the Echelle spectrograph FLECHAS at the
University Observatory Jena in the course of the Grosschwabhausen
binary survey between December 2016 and June 2018. The aim of this
project is to obtain precise RV measurements for spectroscopic binary
stars in order to redetermine, verify, improve, and constrain their
Keplerian orbital solutions. In this paper, we describe the
observations, data reduction, and analysis and present the results of
this project. In total, we have taken 721 RV measurements of 11 stars
and derived well-determined orbital solutions for nine systems (seven
single- and two double-lined spectroscopic binaries) with periods in
the range between 2 and 70 days. In addition, we could rule out the
orbital solutions for the previously classified spectroscopic binary
systems HIP 107136 and HIP 107533, whose radial velocities are found
to be constant on the km/s-level over a span of time of more than
500 days. In the case of HIP 2225, a significant change of its
systematic velocity is detected between our individual observing
epochs, indicating the presence of an additional companion, which is
located on a wider orbit in this system.
Description:
Since 2015 a radial velocity monitoring campaign is going on at the
University Observatory Jena. The aim of this project is to obtain
radial velocity measurements of selected spectroscopic binary systems,
to redetermine and/or constrain their orbital solutions. This is the
continuation of this campaign and the first part of the whole target
sample was published in by Bischoff et al. (2017, Cat. J/AN/338/671).
Here, we present 721 RV measurements of 9 spectroscopic binary systems
as well as HIP 107136 and 107533, taken between 2016 and 2018 at the
University Observatory Jena with the Echelle spectrograph FLECHAS.
