We present the results of V and I photometries for ~56,500 stars of NGC 3109 obtained from a 467.26(')2 wide-field observations. The internal extinction does...
The disc-jet coupling in the neutron star X-ray binary Aquila X-1
We study the accretion/ejection processes (i.e. disc/jet coupling) in the neutron star X-ray binary Aquila X-1 via a multiwavelength approach. We use in the...
The Discovery and Follow-up of Four Transiting Short-period Sub-Neptunes Orbiting M Dwarfs
Sub-Neptunes with radii of 2–3 R ⊕ are intermediate in size between rocky planets and Neptune-sized planets. The orbital properties and bulk compositions of...
The Discovery and Mass Measurement of a New Ultra-short-period Planet: EPIC 228732031b
We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured...
The Discovery of a Companion to the Lowest Mass White Dwarf
We report the detection of a radial velocity companion to SDSS J091709.55+463821.8, the lowest mass white dwarf currently known, with M~0.17 Msolar. The radial...
We report the discovery of a very cool d/sdL7+T7.5p common proper motion binary system, SDSS J1416+13AB, found by cross-matching the United Kingdom Infrared...
We report the discovery of a T8.5 dwarf, which is a companion to the M4 dwarf Wolf 940. At a distance of 12.50+0.75-0.67 pc, the angular separation of 32 arcsec...
The Discovery of Binary White Dwarfs that will Merge Within 500 Myr
We present radial velocity observations of four extremely low-mass (0.2 M sun) white dwarfs (WDs). All four stars show peak-to-peak radial velocity variations...
The Discovery of More than 2000 White Dwarfs in the Globular Cluster ω Centauri
We present deep multiband (F435W, F625W, and F658N) photometric data of the globular cluster ω Cen collected with the Advanced Camera for Surveys on board the...
