Aims. EXor-type objects are protostars that display powerful UV-optical outbursts caused by intermittent and powerful events of magnetospheric accretion. These objects are not yet well investigated and are quite difficult to characterize. Several par

We report time-resolved, high-resolution optical spectropolarimetric observations of the young double-lined spectroscopic binary V1878 Ori. Our observations were collected with the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope thr

X-shooter spectroscopy of young stars with disks. The TW Hydrae association as a probe of the final stages of disk accretion

Autor: Ray Jayawardhana, Brunella Nisini, Simone Antoniucci, Aleks Scholz, Carlo F. Manara, Antonio Frasca, Juan M. Alcalá, Costanza Argiroffi, A. Natta, L. Venuti, Beate Stelzer, Sofia Randich

We investigate ongoing accretion activity in young stars in the TW Hydrae association (TWA, ~8-10 Myr), an ideal target to probe the final stages of disk accretion down to brown dwarf masses. Our sample comprises eleven TWA members with infrared exce

Deep X-ray view of the Class I YSO Elias 29 with XMM-Newton and NuSTAR

Autor: Fabio Reale, Ettore Flaccomio, Giuseppina Micela, Beate Stelzer, Costanza Argiroffi, Ignazio Pillitteri, Salvatore Sciortino

[Abridged] We investigated the X-ray characteristics of the Class I YSO Elias 29 with joint XMM-Newton and NuSTAR observations of 300 ks and 450 ks, respectively. These are the first observations of a very young (7.11$ keV.

Metals form an essential part of the Universe at all scales. Without metals we would not exist, and the Cosmos would look completely different. Metals are primarily born through nuclear processes in stars. They leave their cradles through winds or ex
