A candidate to the long sought optical counterpart to the Rapid Burster in the bulge fossil fragment Liller 1
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +6
We report on the possible identification of the optical counterpart of the Rapid Burster MXB 1730-335 in the stellar system Liller 1. The identification was performed by taking adv…
Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances*
Rohan Rahatgaonkar, Juan Pablo Carvajal, Thomas H. Puzia +25
We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025~N1) from to ~au using X-shooter (300--550\,nm, ) and UVES (opt…
OGLE-2011-BLG-0462: An Isolated Stellar-Mass Black Hole Confirmed Using New HST Astrometry and Updated Photometry
Kailash C Sahu, Jay Anderson, Stefano Casertano +7
The long-duration Galactic-bulge microlensing event OGLE-2011-BLG-0462 produced relativistic astrometric deflections of the source star, which we measured using HST observations ta…
Testing Cluster Membership of Planetary Nebulae with High-Precision Proper Motions. II. HST Observations of PHR J1315-6555 in the Open Cluster AL 1 (ESO 96-SC04)
Andrea Bellini, Howard E. Bond, Kailash C. Sahu
Planetary nebulae (PNe) shown to be members of star clusters provide information on their properties and evolutionary histories that cannot be determined for PNe in the field, in p…
