The Enigma of Gaia18cjb: a Rare Hybrid of FUor and EXor?
Eleonora Fiorellino, Peter Abraham, Agnes Kospal +28
Context. Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU…
2MASS J15491331-3539118: a new low-mass wide companion of the GQ Lup system
J. M. Alcalá, F. Z. Majidi, S. Desidera +14
Substellar companions at wide separation around stars hosting planets or brown dwarfs (BDs) yet close enough for their formation in the circumstellar disc are of special interest.…
X-Shooter spectroscopy of young stellar objects: IV -- Accretion in low-mass stars and sub-stellar objects in Lupus
J. M. Alcalá, A. Natta, C. F. Manara +11
We present X-Shooter/VLT observations of a sample of 36 accreting low-mass stellar and sub-stellar objects (YSOs) in the Lupus star forming region, spanning a range in mass from ~0…
Astrophysical false positives in direct imaging for exoplanets: a white dwarf close to a rejuvenated star
A. Zurlo, A. Vigan, J. Hagelberg +17
As is the case for all techniques involved in the research for exoplanets, direct imaging has to take into account the probability of so-called astrophysical false positives, which…
Crossing the Gould Belt in the Orion vicinity
K. Biazzo, J. M. Alcalá, E. Covino +5
We present a study of the large-scale spatial distribution of 6482 RASS X-ray sources in approximately 5000 deg^2 in the direction of Orion. We examine the astrophysical properties…
Large-scale young Gould Belt stars across Orion
K. Biazzo, J. M. Alcalá, M. F. Sterzik +3
We report first results on the large-scale distribution of the ROSAT All-Sky Survey (RASS) X-ray sources in a 5000 deg^2 field centered on Orion. Our final aim is to study the prop…
IRAS12556-7731: a "chamaeleonic" lithium-rich M-giant
J. M. Alcala', K. Biazzo, E. Covino +2
In this letter we characterise IRAS12556-7731 as the first lithium-rich M-type giant. Based on its late spectral type and high lithium content, and because of its proximity in angu…
