A Deficit of Massive White Dwarfs in Gaia Astrometric Binaries
Na'ama Hallakoun, Sahar Shahaf, Tsevi Mazeh +2
The third data release of Gaia introduced a large catalog of astrometric binaries, out of which about 3,200 are likely main-sequence stars with a white-dwarf (WD) companion. These…
Triage of the Gaia DR3 astrometric orbits. II. A census of white dwarfs
S. Shahaf, N. Hallakoun, T. Mazeh +4
The third data release of Gaia was the first to include orbital solutions assuming non-single stars. Here, we apply the astrometric triage technique of Shahaf et al. to identify bi…
An irradiated-Jupiter analogue hotter than the Sun
Na'ama Hallakoun, Dan Maoz, Alina G. Istrate +10
Planets orbiting close to hot stars experience intense extreme-ultraviolet radiation, potentially leading to atmosphere evaporation and to thermal dissociation of molecules. Howeve…
ULTRASAT: A wide-field time-domain UV space telescope
Y. Shvartzvald, E. Waxman, A. Gal-Yam +41
The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be launched to geostationary orbit in 2026. It will carry a telescope with an unprecedentedly large field o…
The Large Array Survey Telescope -- Science Goals
S. Ben-Ami, E. O. Ofek, D. Polishook +20
The Large Array Survey Telescope (LAST) is designed to survey the variable and transient sky at high temporal cadence. The array is comprised of 48 F/2.2 telescopes of 27.9cm apert…
