Novae, supernovae, or something else? -- (Super-)nova highlights from Hoffmann & Vogt are quite certainly comets (AD 668 and 891)
Ralph Neuhaeuser, Dagmar L. Neuhaeuser, Jesse Chapman
Galactic novae and supernovae can be studied by utilizing historical observations, yielding explosion time, location on sky~etc. Recent publications by Hoffmann & Vogt present CVs,…
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…
New sunspots and aurorae in the historical Chinese text corpus? Comments on uncritical digital search applications
D. L. Neuhaeuser, R. Neuhaeuser, J. Chapman
We review some applications of the method of electronic searching for historical observations of sunspots and aurorae in the Chinese text corpus by Hayakawa et al. etc. However, we…
Solar activity around AD 775 from aurorae and radiocarbon
Ralph Neuhaeuser, Dagmar L. Neuhaeuser
A large variation in 14 C around AD 775 has been considered to be caused by one or more solar super-flares within one year. We critically review all known aurora reports from Europ…
The Hercules-Lyra Association revisited New age estimation and multiplicity study
T. Eisenbeiss, M. Ammler-von Eiff, T. Roell +5
The Her-Lyr assoc., a nearby young MG, contains a few tens of ZAMS stars of SpT F to M. The existence and the properties of the Her-Lyr assoc. are controversial and discussed in th…
The origin of RXJ1856.5-3754 and RXJ0720.4-3125 -- updated using new parallax measurements
Nina Tetzlaff, Thomas Eisenbeiss, Ralph Neuhaeuser +1
RXJ1856 and RXJ0720 are the only young isolated radio-quiet neutron stars (NSs) for which trigonometric parallaxes were measured. Due to detection of their thermal emission in X-ra…
