How magnetic activity alters what we learn from stellar spectra
Lorenzo Spina, Thomas Nordlander, Andrew R. Casey +8
Magnetic fields and stellar spots can alter the equivalent widths of absorption lines in stellar spectra, varying during the activity cycle. This also influences the information th…
A new white dwarf companion to the star GJ 3346
M. Bonavita, C. Fontanive, S. Desidera +7
We present the discovery of a white dwarf companion at 3.6" from GJ3346, a nearby (42 mas) K star observed with SPHERE@VLT as part of an open time survey for faint companion…
The origin of R CrA variability: A complex triple system hosting a disk
E. Sissa, R. Gratton, J. M. Alcala +5
R~CrA is the brightest member of the Coronet star forming region and it is the closest Herbig AeBe star with a spectrum dominated by emission lines. Its luminosity has been monitor…
