Discovery of a Metal-poor, Luminous Post-AGB Star that Failed the Third Dredge-up
D. Kamath, H. Van Winckel, P. R. Wood +4
Post-asymptotic giant branch (post-AGB) stars are known to be chemically diverse. In this paper we present the first observational evidence of a star that has failed the third dred…
Multi-technique investigation of the binary fraction among A-F type candidate hybrid variable stars discovered by Kepler
P. Lampens, Y. Frémat, L. Vermeylen +14
Hundreds of candidate hybrid pulsators of intermediate type A-F were revealed by the recent space missions. Hybrid pulsators allow to study the full stellar interiors, where p- and…
Jet creation in post-AGB binaries: the circum-companion accretion disc around BD+46442
D. Bollen, H. Van Winckel, D. Kamath
We aim at describing and understanding binary interaction processes in systems with very evolved companions. Here, we focus on understanding the origin and determining the properti…
Abundance analyses of the new R Coronae Borealis stars: ASAS-RCB-8 and ASAS-RCB-10
B. P. Hema, Gajendra Pandey, Devika Kamath +3
Abundance analyses of the two newly discovered R Coronae Borealis (RCB) stars ASAS-RCB-8 and ASAS-RCB-10 were conducted using high-resolution optical spectra and model atmospheres.…
SALT HRS discovery of a long period double-degenerate binary in the planetary nebula NGC 1360
B. Miszalski, R. Manick, J. Mikołajewska +3
Whether planetary nebulae (PNe) are predominantly the product of binary stellar evolution as some population synthesis models (PSM) suggest remains an open question. Around 50 shor…
Lithium abundance and rotation of seismic solar analogues - Solar and stellar connection from Kepler and Hermes observations
P. G. Beck, J. -D. do Nascimento, T. Duarte +13
Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. We explore the relation between surface…
