Abstract:
We present the results of our spectroscopic monitoring observations of
the late O-type runaway stars AE Aur and iota Ori, carried out between
September 2016 and May 2018 using the Echelle spectrograph FLECHAS at
the University Observatory Jena. For both stars, we obtained current
radial velocity (RV) measurements with better precision than before.
These results can be used for further advanced calculations of their
space motion, needed to determine, for example, their place of origin
in our Galaxy. In this paper, we describe the observations and the
data reduction, as well as the analysis of all spectral data. We find
a stable RV for AE Aur and confirm iota Ori as a double-lined
spectroscopic binary and derive its current Keplerian orbital
elements.
Description:
Here, we present 95 RV measurements of runaway stars AE Aur and iota
Ori, taken between 2016 and 2018 at the University Observatory Jena
with the Echelle spectrograph FLECHAS.
