Gaia22eor: Symbiotic star V2756 Sgr detected in a deep eclipse

Jaroslav Merc, Hamish Barker, Rudolf Gális

V2756 Sgr is a long-known S-type symbiotic binary that was recently detected in 1 mag eclipse-like fading by the Gaia satellite. This behavior was reported as a Gaia Science…

V410 Puppis: A useful laboratory for early stellar evolution

Ahmet Erdem, Derya Surgit, Burcu Ozkardes +6

New spectrometric (HERCULES) and ground-based multi-colour photometric data on the multiple star V410 Puppis are combined with satellite photometry (HIPPARCOS and TESS), as well as…

Towards a consistent model of the hot quadruple system HD 93206 = QZ Carinæ: II. N-body model

M. Brož, P. Harmanec, P. Zasche +16

HD 93206 is early-type massive stellar system, composed of components resolved by direct imaging (Ab, Ad, B, C, D) as well as a compact sub-system (Aa1, Aa2, Ac1, Ac2). Its geometr…

An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…
