Lucky spectroscopy, an equivalent technique to Lucky Imaging: II. Spatially-resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
J. Maíz Apellániz, R. H. Barbá, C. Fariña +5
CONTEXT. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. AIMS. We want to continue obtaining spatially resolved spectro…
High-resolution spectroscopic study of massive blue and red supergiants in Per OB1
A. de Burgos, S. Simón-Díaz, D. J. Lennon +5
The Perseus OB1 association hosts one of the most populous groupings of blue and red supergiants (Sgs) in the Galaxy. We discuss whether the massive O-type and blue/red Sg stars lo…
V1460 Her: A fast spinning white dwarf accreting from an evolved donor star
R. P. Ashley, T. R. Marsh, E. Breedt +6
We present time-resolved optical and ultraviolet spectroscopy and photometry of V1460~Her, an eclipsing cataclysmic variable with a 4.99\,h orbital period and an overluminous K5-ty…
The post-common-envelope binary central star of the planetary nebula PN G283.7-05.1: A possible post-red-giant-branch planetary nebula central star
David Jones, Henri M. J. Boffin, Jacob Hibbert +8
We present the discovery and characterisation of the post-common-envelope central star system in the planetary nebula PN G283.705.1. Deep images taken as part of the POPIPlaN su…
