Challenging historical novae: AT Cnc (1645), Te-11 (483), and M22 (BC 48) revisited
D. L. Neuhäuser, R. Neuhäuser, V. Hambaryan +2
Connections between novae with shells and historical observations are crucial for astrophysical understanding of long-term evolution of shells and cataclysmic variables. Three of f…
Spectroscopic Follow-Up of Candidate Runaway Stars
Guillermo Torres, Ralph Neuhäuser, Sebastian A. Hüttel +1
Runaway stars are characterized by higher space velocities than typical field stars. They are presumed to have been ejected from their birth places by one or more energetic mechani…
YETI follow-up observations of the T Tauri star CVSO30 with transit-like dips
R. Bischoff, St. Raetz, M. Fernández +13
The T Tauri star CVSO30, also known as PTFO8-8695, was studied intensively with ground based telescopes as well as with satellites over the last decade. It showed a variable light…
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…
The Age of the Carina Young Association and Potential Membership of HD 95086
Mark Booth, Carlos del Burgo, Valeri V. Hambaryan
Carina is a nearby young stellar association. So far, only a small number of stars have been clearly identified as members of this association. In this paper we reanalyse the membe…
A nearby recent supernova that ejected the runaway star zeta Oph, the pulsar PSRB1706-16, and 60-Fe found on Earth
Ralph Neuhaeuser, Frank Gießler, Valeri V. Hambaryan
The detection of Myr old Fe on Earth indicates recent nearby core-collapse supernovae. For supernovae in multiple stars, the primary stars may become neutron…
