Deep JWST/NIRCam imaging of Supernova 1987A
Mikako Matsuura, M. Boyer, Richard G. Arendt +46
JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
Evidence of a substellar companion to AB Dor C
J. B. Climent, J. P. Berger, J. C. Guirado +5
Studies of fundamental parameters of very low-mass objects are indispensable to provide tests of stellar evolution models that are used to derive theoretical masses of brown dwarfs…
Molecular line study of the S-type AGB star W Aquilae. ALMA observations of CS, SiS, SiO and HCN
Magdalena Brunner, Taissa Danilovich, Sofia Ramstedt +5
Context. With the outstanding spatial resolution and sensitivity of the Atacama Large Millimeter/sub-millimeter Array (ALMA), molecular gas other than the abundant CO can be observ…
Magnetically aligned dust and SiO maser polarization in the envelope of the red supergiant VY CMa
W. H. T. Vlemmings, T. Khouri, I. Marti-Vidal +9
We use Atacama Large Millimeter/submillimeter Array Band 5 science verification observations of the red supergiant VY CMa to study the polarization of SiO thermal/masers lines and…
Young, active radio stars in the AB Doradus moving group
R. Azulay, J. C. Guirado, J. M. Marcaide +5
Context. Precise determination of stellar masses is necessary to test the validity of pre-main-sequence (PMS) stellar evolutionary models, whose predictions are in disagreement wit…
Dynamical masses of the low-mass stellar binary ABDoradusB
R. Azulay, J. C. Guirado, J. M. Marcaide +8
Context. ABDoradus is the main system of the ABDoradus moving group. It is a quadruple system formed by two widely separated binaries of pre-main-sequence (PMS) stars: ABDor A/C an…
