We report the discoveries of low-mass free-floating planet (FFP) candidates from the analysis of 2006-2014 MOA-II Galactic bulge survey data. In this data set, we found 6111...

Eclipsing binary systems provide the opportunity to measure fundamental parameters of their component stars in a stellar-model independent way. This makes them ideal candidates...

We analyzed the relationship between several basic parameters describing supermassive black holes such as jet power, black hole spin, accretion disk magnetic field, black hole...

Pulsar polarization profiles form a very basic database for understanding the emission processes in a pulsar magnetosphere. After careful polarization calibration of the 19-beam...

We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5yr. This source has been in quiescence since its...

Star formation is essential in galaxy evolution and the cycling of matter. The support of interstellar clouds against gravitational collapse by magnetic (B-) fields has been...

The latest source catalog of the Fermi-LAT telescope contains more than 7000 gamma-ray sources at GeV energies, with the two dominant source classes thought to be blazars and...

In this work, we present a constraint on the abundance of supergiant (SG) stars at redshift z~1, based on recent observations of a strongly lensed arc at this redshift. First we...

Low-mass X-ray binaries (LMXBs) are high-energy sources that require multi-wavelength follow-up campaigns to be fully characterised. New transients associated with LMXBs are...

The Ninth Catalogue of Spectroscopic Binary Orbits continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators...

This service provides the physical and dynamical characteristics of natural satellites in the Solar System: size, mass, rotational properties, magnitude and albedo, orbital...

The time-series component of Wide-field Infrared Survey Explorer (WISE) is a valuable resource for the study of variable objects. We present an analysis of an all-sky sample of...

Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches...

We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals...

The Gaia mission is delivering a large number of astrometric orbits for binary stars. By combining these with spectroscopic orbits for systems with two observable spectra (SB2),...

The time delay between multiple images of strongly lensed quasars is a powerful tool for measuring the Hubble constant (H0). To achieve H0 measurements with higher precision and...

This catalogue is a compilation of all known AGNs presented in a compact and convenient form. It is an update of the previous versions; and as in the previous editions no...

This catalogue is an update of the previous versions; as in the previous editions no information about absorption lines of X-ray properties are given, but absolute magnitudes...

This catalog is abstracted from the Card Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...

The catalogue contains all stars listed in the 7th Catalogue of Spectroscopic Binaries (Batten, 1967PDAO...13..119B), supplements by Pedoussaut et al.: 1971A&AS....4..253P...
