HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
D. G. Whelan, S. D. Chojnowski, J. Labadie-Bartz +13
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission…
Evolution of the disk of pi Aqr: from near-disappearance to a strong maximum
Y. Naze, G. Rauw, J . Guarro Flo +30
Some Be stars display important variability of the strength of the emission lines formed in their disk. This is notably the case of pi Aqr. We present here the recent evolution of…
HD 63021: An Ae Star with X-ray Flux
David G. Whelan, Jon Labadie-Bartz, S. Drew Chojnowski +2
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 absorp…
