The team estimated the mass by observing the speed of a representative sample of stars in each galaxy. (sciencemag.org)
In this case, researchers estimated the mass of the black hole would be 36 times the solar mass or larger. (sciencedaily.com)
From a transit - based estimate of the host star's mean density, combined with analysis of high - resolution spectra, we infer that the host star is near turnoff from the main sequence, with estimated mass and radius of 1.223 (+0.053 -0.091) solar masses and 1.487 (+0.071 -0.084) solar radii.
