New constraints on the binary system HD 327083 and its gaseous and dusty environments
L. Cidale, P. Marchiano, M. Kraus +11
Binary systems with circumbinary molecular and dust rings are of great interest because they provide insights into the dynamics and evolution of stellar systems and the chemistry o…
BCD spectrophotometry for massive stars in transition phases
Y. J. Aidelman, M. Borges Fernandes, L. S. Cidale +7
Context. Stars in transition phases, like those showing the B[e] phenomenon and luminous blue variables (LBVs), undergo strong, often irregular mass ejection events. The prediction…
Simultaneous J-, H-, K- and L-band spectroscopic observations of galactic Be stars. I. IR atlas
Y. R. Cochetti, M. L. Arias, L. S. Cidale +2
It is already accepted that Be stars are surrounded by circumstellar envelopes, which are mostly compatible with a disc geometry in Keplerian rotation. We aim to obtain a more comp…
Intriguing detection of CO molecular emission in a classical Be star
Y. R. Cochetti, M. L. Arias, M. Kraus +4
In the group of B stars with spectroscopic peculiarities, we can find the Be and the B[e] stars. The Be stars are early-type rapid rotators that present, as their principal charact…
Near-infrared characterization of four massive stars in transition phases
Yanina R. Cochetti, Michaela Kraus, María L. Arias +5
Massive stars typically undergo short-lived post-main sequence evolutionary phases with strong mass loss and occasional mass eruptions. Many of such massive stars in transition pha…
Be and Bn stars: Balmer discontinuity and stellar-class relationship
Y. R. Cochetti, J. Zorec, L. S. Cidale +5
A significant number of Be stars show a second Balmer discontinuity (sBD) attributed to an extended circumstellar envelope (CE). The fast rotational velocity of Be stars undoubtedl…
Spectro-interferometric observations of a sample of Be stars. Setting limits to the geometry and kinematics of stable Be disks
Y. R. Cochetti, C. Arcos, S. Kanaan +3
Be stars are rapid rotators surrounded by a gaseous disk envelope whose origin is still under debate. This envelope is responsible for observed emission lines and large infrared ex…
