OGLE-2015-BLG-1395Lb: A Cold Sub-Saturn Mass Planet Orbiting an M Dwarf

Andrew A. Cole, Joshua W. Blackman, Jean-Philippe Beaulieu +75

We present an analysis of the high-magnification microlensing event OGLE-2015-BLG-1395 and report the discovery of a sub-Saturn mass companion to the lens. Photometric coverage of…

Brightness, Colour, Polarisation: A Multi-Instrument Observation Campaign of the Gorizont-6 Satellite

Robert J. S Airey, Paul Chote, Klaas Wiersema +15

We present a coordinated multi-instrument photometric and polarimetric study of the defunct geosynchronous satellite, Gorizont-6. This observation campaign combined wide-field mult…

OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host

M. J. Mróz, R. Poleski, A. Udalski +70

We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri

Gaia Collaboration, K. Weingrill, A. Mints +400

Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…

Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment

Gaia Collaboration, P. David, F. Mignard +2

Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…

Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars

Gaia Collaboration, A. Krone-Martins, C. Ducourant +398

Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…

Gaia Focused Product Release: Radial velocity time series of long-period variables

Gaia Collaboration, M. Trabucchi, N. Mowlavi +403

The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…

Discovery of a Cool Planet of 5.5 Earth Masses Through Gravitational Microlensing

J. -P. Beaulieu, D. P. Bennett, P. Fouque +46

In the favoured core-accretion model of formation of planetary systems, solid planetesimals accumulate to build up planetary cores, which then accrete nebular gas if they are suffi…
