Monday 18 November marked two years since Gaia was found dead following an 11 day disappearance and mass public search. During the anniversary of her disappearance (7-18 November) supporters and members of the public have lit candles in Gaia’s memory, some shared on social media with the has...
In this work, I demonstrate (quantitatively) how our ignorance extends, and point out the importance of discovering and studying systems like Gaia BH1. In addition, an approximate mass–temperature relation and mass ratio–magnitude difference relation for main-sequence stars...
Figure 2 shows the VPM diagrams for sources with Ks 15 mag matched in the 2MASSGaia catalogues, and sources with Ks 13 mag matched in the VVVX Gaia 2. Discovery of Garro01 catalogues, respectively. In the same Figure, the stars located outside 1 mas yr1 circle selected on the VPM ...
Since DR1 did not provide colours for its sources, the 2MASS photometry [59] of the identified members was used and analysed with the automated isochrone fitting tool BASE-9 [60]. Their work was, however, limited to 128 nearby and prominent clusters, mostly located within 1 kpc of the ...
3. Gaia BH1—A Rare Low-q Binary InSection 2, it was shown that we have a notable lack of information about low-q systems. From this point of view, the Gaia BH1 is a very valuable finding, the importance of which cannot be underestimated. Indeed, the mass of the black hole indicat...

The recently discovered Gaia BH1 binary system, a Sun-like star and a dark object (presum- ably a black hole), may significantly change our understanding of the population of binaries. The paper presents the components mass ratio (q) distributions of binary systems of different observational ...
