Vampire Star’s Feeding Ground: First X-ray Peek at a White Dwarf’s Hungry Binary
What scientists are calling a “vampire star” system In a striking demonstration of how extreme physics unfolds in binary stars, researchers have captured the first detailed look at the inner region around a dead white dwarf siphoning material from a nearby stellar companion. Using NASA’s Imaging X-ray Polarimetry Explorer (IXPE), the team has observed how…

Transiting Planets in Binaries II: A Dichotomy in Orbital Alignment of Small Planets in Close Binary Systems
Introduction Stellar multiplicity has long been recognized as a key factor shaping how planets form and evolve. Building on a survey of nearby systems, this study focuses on transiting planets found in binary hosts and leverages significant Hipparcos-Gaia astrometric accelerations to identify and characterize companions. In particular, we examine 54 TESS Objects of Interest (TOIs)…
