Intermediate-Mass Mergers: A New Scenario for Several FS CMa Stars
Daniela Korcakova, Nela Dvorakova, Iris Bermejo Lozano +6
We summarise the properties and nature of a peculiar group of B-type stars called FS CMa stars. These stars show the B[e] phenomenon, i.e., their spectra exhibit both forbidden emi…
Constraining the Stellar Masses and Origin of the Protostellar VLA 1623 System
Sarah I Sadavoy, Patrick Sheehan, John J. Tobin +6
We present ALMA Band 7 molecular line observations of the protostars within the VLA 1623 system. We map CO (3 - 2) in the circumbinary disk around VLA 1623A and the outflow…
A magnetic massive star has experienced a stellar merger
A. J. Frost, H. Sana, L. Mahy +13
Massive stars (those larger than 8 solar masses at formation) have radiative envelopes that cannot sustain a dynamo, the mechanism that produces magnetic fields in lower-mass stars…
Finding magnetic north: an extraordinary magnetic field detection in Polaris and first results of a magnetic survey of classical Cepheids
James A. Barron, Gregg A. Wade, Nancy R. Evans +2
Classical Cepheids are essential objects in the study of stellar evolution and cosmology; however, we know little about their magnetic properties. We report the detection of Stokes…
Untangling magnetic massive star properties with linear polarization variability and the Analytic Dynamical Magnetosphere model
M. S. Munoz, G. A. Wade, D. M. Faes +2
Light scattered off particles can become linearly polarized. Stars surrounded by oblique, co-rotating envelopes are therefore expected to manifest periodic linear polarimetric vari…
HAWC+/SOFIA Polarimetry in L1688: Relative Orientation of Magnetic Field and Elongated Cloud Structure
Dennis Lee, Marc Berthoud, Che-Yu Chen +14
We present a study of the relative orientation between the magnetic field and elongated cloud structures for the Oph A and Oph E regions in L1688 in the Ophiuchus molecular…
