Two's company, three's a crowd: SALT reveals the likely triple nature of the nucleus of the extreme abundance discrepancy factor planetary nebula Sp 3
B. Miszalski, R. Manick, T. Rauch +3
The substantial number of binary central stars of planetary nebulae (CSPNe) now known (50) has revealed a strong connection between binarity and some morphological features i…
GK Car and GZ Nor: Two low-luminous, depleted RV Tauri stars
I. Gezer, H. Van Winckel, R. Manick +1
We performed a photometric and spectroscopic analysis of two RV Tauri stars GK Car and GZ Nor. Both objects are surrounded by hot circumstellar dust. Their pulsation periods, deriv…
The spectroscopic binaries RV Tauri and DF Cygni
Rajeev Manick, Devika Kamath, Hans Van Winckel +7
Aim: The focus of this paper is on two famous but still poorly understood RV Tauri stars: RV Tau and DF Cyg. We aim at confirming their suspected binary nature and deriving their o…
The post-common-envelope binary nucleus of the planetary nebula IC~4776: Neither an anomalously long orbital period nor a Wolf-Rayet binary
B. Miszalski, R. Manick, H. Van Winckel +1
The orbital period distribution of close binary stars consisting of a white dwarf and a main-sequence star (WDMS) is a powerful observational constraint on population synthesis mod…
Barium & related stars and their white-dwarf companions II. Main-sequence and subgiant stars
A. Escorza, D. Karinkuzhi, A. Jorissen +12
Barium (Ba) dwarfs and CH subgiants are the less-evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by a binary companion…
The post-common-envelope X-ray binary nucleus of the planetary nebula NGC 2392
Brent Miszalski, Rajeev Manick, Hans Van Winckel +1
The Chandra X-ray Observatory has detected relatively hard X-ray emission from the central stars of several planetary nebulae (PNe). A subset have no known late-type companions, ma…
Resolved imaging of the AR Puppis circumbinary disk
S. Ertel, D. Kamath, M. Hillen +14
Circumbinary disks are common around post-asymptotic giant branch (post-AGB) stars with a stellar companion on orbital time scales of a few 100 to few 1000 days. The presence of a…
