The deep eclipses of RW Aur revisited by long-term photometric and spectroscopic monitoring
O. Lux, M. Mugrauer, R. Bischoff
RW Aurigae is a young stellar system containing a classical T Tauri star as the primary component. It shows deep, irregular dimmings, first detected in 2010. At the University Obse…
The origin of the high-mass X-ray binary 4U 2206+54/BD +53 2790
V. Hambaryan, K. A. Stoyanov, M. Mugrauer +7
Based on the Gaia EDR3 astrometric parameters and our new systemic radial velocity of the high-mass X-ray binary 4U 2206+54/BD+53 2790, we studied the trace back motion of the syst…
Identification of additional young nearby runaway stars based on Gaia data release 2 observations and the lithium test
R. Bischoff, M. Mugrauer, G. Torres +4
Runaway stars are characterised by their remarkably high space velocities, and the study of their formation mechanisms has attracted considerable interest. Young, nearby runaway st…
A search for runaway stars in twelve Galactic supernova remnants
O. Lux, R. Neuhäuser, M. Mugrauer +1
Runaway stars can result from core-collapse supernovae in multiple stellar systems. If the supernova disrupts the system, the companion gets ejected with its former orbital velocit…
Spectroscopic orbit determination of the long-periodic binary system Cep
R. Bischoff, M. Mugrauer, O. Lux +4
In 2015 a radial velocity monitoring campaign was started in order to redetermine and/or constrain the orbital solutions of spectroscopic binary systems. The observations were carr…
Identification of young nearby runaway stars based on Gaia data and the lithium test
R. Bischoff, M. Mugrauer, G. Torres +6
Young nearby runaway stars are suitable to search for their place of origin and possibly associated objects, for example neutron stars. Tetzlaff, Neuhäuser & Hohle (2011) selected…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
Spectroscopic characterization of nine binary star systems as well as HIP107136 and HIP107533
T. Heyne, M. Mugrauer, R. Bischoff +6
We present the results of our 2nd radial velocity monitoring campaign, carried out with the Échelle spectrograph FLECHAS at the University Observatory Jena in the course of the Gro…
Diagnosing the Clumpy Protoplanetary Disk of the UXor Type Young Star GM Cephei
P. C. Huang, W. P. Chen, M. Mugrauer +29
UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM\,Cephei is such a UXor in the young (~M…
The Radial and Rotational Velocity of Ophiuchi
T. Zehe, M. Mugrauer, R. Neuhäuser +5
We present the results of our spectroscopic monitoring campaign of Oph, carried out at the University observatory Jena with the spectrograph FLECHAS between July 2015 and Septe…
Radial velocity measurements and orbit determination of eight single-lined spectroscopic binary systems
R. Bischoff, M. Mugrauer, T. Zehe +7
Since early 2015 a new radial velocity monitoring campaign is going on at the University Observatory Jena. The aim of this project is to obtain current radial velocity measurements…
