Colour evolution of Betelgeuse and Antares over two millennia, derived from historical records, as a new constraint on mass and age

Ralph Neuhäuser, Guillermo Torres, Markus Mugrauer +4

After core hydrogen burning, massive stars evolve from blue-white dwarfs to red supergiants by expanding, brightening, and cooling within few millennia. We discuss a previously neg…

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…

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…

Long-Term Photometry of IC 348 with the YETI Network

D. J. Fritzewski, M. Kitze, M. Mugrauer +29

We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…

The spectacular evolution of Supernova 1996al over 15 years: a low energy explosion of a stripped massive star in a highly structured environment

Stefano Benetti, Nikolai N. Chugai, Victor P. Utrobin +9

Spectrophotometry of SN 1996al carried out throughout 15 years is presented. The early photometry suggests that SN 1996al is a Linear type-II supernova, with an absolute peak of Mv…
