Radial Velocity Monitoring and Analysis of Gaia Astrometry of Selected Intermediate Mass Stars to Constrain Their Multiplicity Status
J. Bätz, M. Mugrauer, K. -U. Michel +5
We present new radial velocity measurements of 13 selected intermediate mass stars (2 - 6 M). The measurements were performed between 29 April and 6 September 2024 at the U…

The Mira discovery problem -- Observations by David Fabricius in 1596 and 1609 (and by others before?): Positional accuracy, brightness, color index, and period
R. Neuhäuser, D. L. Neuhäuser, M. Mugrauer +2
The pulsating variable star Mira (omikron Ceti) was observed by David Fabricius (Frisia) in 1596 and 1609. We review suggested previous detections (e.g. China, Hipparchos). We anal…
