Chandra measurements of gas homogeneity and turbulence at intermediate radii in the Perseus Cluster
Martijn de Vries, Adam B. Mantz, Steven W. Allen +6
We present a Chandra study of surface brightness fluctuations in the diffuse intracluster medium of the Perseus Cluster. Our study utilizes deep, archival imaging of the cluster co…
Analysis of photometric and spectroscopic variability of red supergiant Betelgeuse
Daniel Jadlovsky, Jiri Krticka, Ernst Paunzen +1
Betelgeuse is a pulsating red supergiant whose brightness is semi periodically variable and in February 2020 reached a historical minimum, the Great Dimming. The aims of this study…
Testing a scaling relation between coherent radio emission and physical parameters of hot magnetic stars
Barnali Das, Poonam Chandra, Matt E. Shultz +4
Coherent radio emission via electron cyclotron maser emission (ECME) from hot magnetic stars was discovered more than two decades ago, but the physical conditions that make the gen…
Searching for shell stars in LAMOST DR4 by probing the Fe 42 multiplet lines
S. Huemmerich, E. Paunzen, K. Bernhard
Shell stars, in particular the cooler ones, often do not show conspicuous Balmer-line emission and may consequently be missed in surveys that specifically search for emission signa…
Modelling Cosmic Radiation Events in the Tree-ring Radiocarbon Record
Qingyuan Zhang, Utkarsh Sharma, Jordan A. Dennis +6
Annually-resolved measurements of the radiocarbon content in tree-rings have revealed rare sharp rises in carbon-14 production. These 'Miyake events' are likely produced by rare in…
The detection of magnetic chemically peculiar stars using Gaia BP/RP spectra
E. Paunzen, M. Prisegen
The magnetic chemically peculiar (mCP) stars of the upper main sequence are perfectly suited to studying the effects of rotation, diffusion, mass-loss, accretion, and pulsation in…
