A wide star-black-hole binary system from radial-velocity measurements

Jifeng Liu, Haotong Zhang, Andrew W. Howard +52

All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…

A Finite-Geometric Classification of Three-Qubit Mermin Pentagrams

Metod Saniga, Frederic Holweck, Hamza Jaffali

Given the facts that the three-qubit symplectic polar space features three different kinds of observables and each of its labeled Fano planes acquires a definite sign, we found tha…

HST/COS Spectra of the Wind Lines of VFTS 102 and 285

Katherine Shepard, Douglas R. Gies, Kathryn V. Lester +5

Rapid rotation in massive stars imposes a latitudinal variation in the mass loss from radiatively driven winds that can lead to enhanced mass loss at the poles (with little angular…

Periodic transit timing variations and refined system parameters of the exoplanet XO-6b

Zoltán Garai, Theodor Pribulla, Richard Komžík +3

Only a few exoplanets are known to orbit around fast rotating stars. One of them is XO-6b, which orbits an F5V-type star. Shortly after the discovery, we started multicolor photome…
