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…
