A Search for the modern counterparts of the Far Eastern guest stars 369 CE, 386 CE, and 393 CE
Susanne M Hoffmann, Nikolaus Vogt
In this study, we apply our previously developed method to investigate ancient transient sightings in order to derive consequences for modern astrophysical problems.We present case…
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…
The genesis of Hippachus' celestial globe
Susanne M Hoffmann
This paper summarises briefly and in English some of the results of the book Hoffmann: Hipparchs Himmelsglobus, Springer, 2017 that had to be written in German. The globe of Hippar…
Counterparts of Far Eastern Guest Stars: Novae, supernovae, or something else?
Susanne M Hoffmann, Nikolaus Vogt
Historical observations of transients are crucial for studies of their long-term evolution. This paper forms part of a series of papers in which we develop methods for the analysis…
Cataclysmic variables as possible counterparts of ancient Far Eastern guest stars
Susanne M Hoffmann, Nikolaus Vogt
Continuing our efforts to select possible classical nova candidates among Far Eastern guest stars and to identify them with modern cataclysmic variables (CVs), we present a search…
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…
