TL;DR
This paper reports the discovery of emission lines and X-ray flux in HD 63021, suggesting it may have a strong stellar wind or a compact binary companion, with further studies planned.
Contribution
First identification of emission lines and X-ray emission in HD 63021, indicating complex stellar activity or binarity.
Findings
Detection of Balmer and Fe II emission lines
Observation of variability in spectral lines
X-ray luminosity suggests stellar wind or binary companion
Abstract
Balmer and Fe II (42) multiplet emission were discovered in a spectrum of HD 63021 on 10 April (UTC), 2018. Subsequent observations revealed variability in both photospheric absorption lines and Balmer line emission. In addition, it is an X-ray source, with a luminosity that is consistent with either a very strong stellar wind, or else the presence of a compact binary companion. Spectroscopic and photometric followup are planned to determine the nature of this source.
