The Gaia-ESO Survey: A new diagnostic for accretion and outflow activity in the young cluster NGC 2264
(European Southern Observatory, 2020)
Context. NGC 2264 is a young cluster whose accretion properties can be investigated in detail by taking advantage of the FLAMES data in the context of the Gaia-ESO Survey. In fact, the analysis of the Hα emission line ...
Magnetic field and wind of kappa ceti: toward the planetary habitability of the young sun when life arose on earth
(The American Astronomical Society, 2020)
Study of the inner dust envelope and stellar photosphere of the AGB star R Doradus using SPHERE/ZIMPOL
(EDP Sciences, 2016)
Context. On the asymptotic giant branch (AGB) low-and intermediate-mass stars eject a large fraction of their envelope, but the mechanism driving these outflows is still poorly understood. For oxygen-rich AGB stars, the ...
X-ray emission from Eta Carinae near periastron in 2009. I. A two state solution
(American Astronomical SocietyChicago, 2014)
X-ray emission from the supermassive binary system η Car declines sharply around periastron. This X-rayminimum
has two distinct phases—the lowest flux phase in the first ∼3 weeks and a brighter phase thereafter. In 2009, ...
ALMA observations of anisotropic dust mass loss in the inner circumstellar environment of the red supergiant VY Canis Majoris
(EDP Sciences, 2015)
The processes leading to dust formation and the subsequent role it plays in driving mass loss in cool evolved stars is an area of intense study. Here we present high resolution ALMA Science Verification data of the continuum ...
