The OVz stars in NGC 346: distribution, stellar parameters and insights into low-metallicity effects
Leidy Arango, Julia Arias, Gonzalo Holgado +3
OVz stars are identified by their optical spectra, in which the He II 4686 absorption line is stronger than any other He line. This spectral characteristic suggests that these star…
SN 2024ggi: another year, another striking Type II supernova
K. Ertini, T. A. Regna, L. Ferrari +19
SN 2024ggi is a Type II supernova that exploded in the nearby galaxy NGC 3621 at a distance of approximately 7 Mpc, making it one of the closest supernovae of the decade. This SN s…
Non-synchronous rotations in massive binary systems. HD93343 revisited
C. Putkuri, R. Gamen, N. I. Morrell +5
Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as doublelined spectroscopic binaries and among these, the OWN Survey has de…
Spectroscopic and photometric analysis of the early-type spectroscopic binary HD 161853 in the centre of an H II region
R. Gamen, C. Putkuri, N. I. Morrell +6
We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system. We secured high-resolution spectra of HD 161853 during the past nin…
