The mass of CoRoT-7b, the first transiting super-Earth exoplanet, is still a subject of debate. A wide range of masses have been reported in the literature...
The mass of our Galaxy from satellite proper motions in the Gaia era
We use Gaia DR2 systemic proper motions of 45 satellite galaxies to constrain the mass of the Milky Way using the scale-free mass estimator of Watkins et al....
The mass of the black hole in GS 2000+25 (=QZ Vul).
The authors report the first infrared light curve of GS 2000+25. By modelling the brightness variations as ellipsoidal modulations of the secondary star, the...
The mass of the black hole in the low-inclination LMXB transient system GRO J0422+32 (=Nova Persei 1992)
We present the first infrared light curve of GRO J0422+32, and use it along with R-band data and published I- and Cousins R_c-band data to constrain the...
We present a direct determination of the mass of the system components in the soft X-ray transient A0620 -00. Infrared photometry during 1990 allows us to...
The Mass of the Neutron Star in Cygnus X-2 (V1341 Cygni)
Cygnus X-2 is one of the brightest and longest known X-ray sources. We present high-resolution optical spectroscopy of Cyg X-2 obtained over 4 yr, which gives...
The mass of TOI-519 b: A close-in giant planet transiting a metal-rich mid-M dwarf
We report on the determination of the mass of TOI-519 b, a transiting substellar object around a mid-M dwarf. We carried out radial velocity measurements using...
The mass of X-ray Nova Scorpii1994 (=GRO J1655-40)
We have obtained high- and intermediate-resolution optical spectra of the black hole candidate Nova Scorpii 1994 in 1998 May/June, when the source was in...
