The spin rates of O stars in WR + O Magellanic Cloud binaries
Michael M. Shara, Steven M. Crawford, Dany Vanbeveren +3
Some massive, merging black holes (BH) may be descendants of binary O stars. The evolution and mass transfer between these O stars determines the spins of their progeny BH. These w…
Revisiting the pulsational characteristics of the exoplanet host star Pictoris
K. Zwintz, D. R. Reese, C. Neiner +22
Exoplanet properties crucially depend on their host stars' parameters. In case the exoplanet host star shows pulsations, asteroseismology can be used for an improved description of…
Discovery of δ Scuti Pulsations in the Young Hybrid Debris Disk Star HD 156623
Samuel N. Mellon, Eric E. Mamajek, Konstanze Zwintz +11
The bRing robotic observatory network was built to search for circumplanetary material within the transiting Hill sphere of the exoplanet Pic b across its bright host star …
The spin rates of O stars in WR + O binaries. I. Motivation, methodology and first results from SALT
Michael M. Shara, Steven M. Crawford, Dany Vanbeveren +3
The black holes (BH) in merging BH-BH binaries are likely progeny of binary O stars. Their properties, including their spins, will be strongly influenced by the evolution of their…
Abell 48 - a rare WN-type central star of a planetary nebula
H. Todt, A. Y. Kniazev, V. V. Gvaramadze +18
A considerable fraction of the central stars of planetary nebulae (CSPNe) are hydrogen-deficient. Almost all of these H-deficient central stars (CSs) display spectra with strong ca…
Possible detection of two giant extrasolar planets orbiting the eclipsing polar UZ Fornacis
Stephen B. Potter, Encarni Romero--Colmenero, Gavin Ramsay +11
We present new high-speed, multi-observatory, multi-instrument photometry of the eclipsing polar UZ For in order to measure precise mid-eclipse times with the aim of detecting any…
