New Arabic records from Cairo on supernovae 1181 and 1006
J. G. Fischer, H. Halm, R. Neuhäuser +1
The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000-5000 yr), the unusual star IRAS 00500+67…
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…
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…
