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…
The eccentric short-period orbit of the supergiant fast X-ray transient HD 74194 (=LM Vel)
R. Gamen, R. H. Barbá, N. R. Walborn +5
Aims. We present the first orbital solution for the O-type supergiant star HD 74194, which is the optical counterpart of the supergiant fast X-ray transient IGR J08408-4503. Method…
The little-studied cluster Berkeley 90. II. The foreground ISM
J. Maíz Apellániz, R. H. Barbá, A. Sota +1
Context: Nearly one century after their discovery, the carrier(s) of Diffuse Interstellar Bands is/are still unknown and there are few sightlines studied in detail for a large numb…
Broad Balmer Wings in BA Hyper/Supergiants Distorted by Diffuse Interstellar Bands: Five Examples in the 30 Doradus Region from the VLT-FLAMES Tarantula Survey
Nolan R. Walborn, Hugues Sana, Christopher J. Evans +11
Extremely broad emission wings at H and H have been found in VFTS data for five very luminous BA supergiants in or near 30 Doradus in the Large Magellanic Cloud. The profiles…
Spectral Variations of Of?p Oblique Magnetic Rotator Candidates in the Magellanic Clouds
Nolan R. Walborn, Nidia I. Morrell, Yael Naze +7
Optical spectroscopic monitoring has been conducted of two O stars in the Small and one in the Large Magellanic Cloud, the spectral characteristics of which place them in the Of?p…
The little-studied cluster Berkeley 90. I. LS III +46 11: a very massive O3.5 If* + O3.5 If* binary
J. Maíz Apellániz, I. Negueruela, R. H. Barbá +9
Context: It appears that most (if not all) massive stars are born in multiple systems. At the same time, the most massive binaries are hard to find due to their low numbers through…
