Dual and lensed AGN at sub-arcsecond separations uncovered by ERIS
M. V. Zanchettin, F. Mannucci, Q. D'Amato +62
We present the first results of the ongoing INAF GTO program focused on the search of sub-arcsecond dual AGN, carried out with the near-infrared integral-field unit SPIFFIER of the…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
VLTI-GRAVITY measurements of cool evolved stars: II. Pulsation properties and mass-loss process of the Mira star R Car and the red supergiant VX Sgr
D. Jadlovský, M. Wittkowski, A. Chiavassa +9
The mass-loss process of red supergiant (RSG) and asymptotic giant branch (AGB) stars and its relation to variability are poorly constrained. We study two evolved stars, the Mira-t…
The VLT/ERIS grating vector Apodizing Phase Plate coronagraph
M. A. Kenworthy, F. A. Dannert, J. Hayoz +29
We describe the design, laboratory manufacture, and on-sky testing of the grating vector apodizing phase plate (gvAPP) coronagraph for the Enhanced Resolution Imager and Spectrogra…
Betelgeuse: Detection of the Expanding Wake of the Companion Star
Andrea K. Dupree, Paul I. Cristofari, Morgan MacLeod +1
Recent analyses conclude that Betelgeuse, a red supergiant star (HD 39801), likely has a companion object with a period of about 2000 days orbiting at only 2.3 stellar radii, deep…
