On the characterization of GJ 504: a magnetically active planet-host star observed by the Transiting Exoplanet Survey Satellite (TESS)
Maria Pia Di Mauro, Raffaele Reda, Savita Mathur +10
We present the results of the analysis of the photometric data collected in long and short-cadence mode by the Transiting Exoplanet Survey Satellite (TESS) for GJ 504, a well studi…
Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars
M. Bonavita, C. Fontanive, R. Gratton +6
The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
A triple star in disarray -- Multi-epoch observations of T Tauri with VLT-SPHERE and LBT-LUCI
M. Kasper, K. K. R. Santhakumari, T. M. Herbst +24
T Tauri remains an enigmatic triple star for which neither the evolutionary state of the stars themselves, nor the geometry of the complex outflow system is completely understood.…
Characterization of very wide companion candidates to young stars with planets and disks
F. Z. Majidi, S. Desidera, J. M. Alcalá +6
Discovering wide companions of stellar systems allows us to constrain the dynamical environment and age of the latter. We studied four probable wide companions of four different st…
The circumstellar environment of EX Lup: the SPHERE and SINFONI views
E. Rigliaco, R. Gratton, A. Kospal +15
EX Lup is a well-studied T Tauri star that represents the prototype of young eruptive stars EXors. In this paper we analyze new adaptive optics imaging and spectroscopic observatio…
