Vampire Star Unveiled: IXPE Reveals Feeding in a Dead White Dwarf System
Scientists Catch the First Glimpse of a ‘Vampire Star’ Feeding on Its Victim In a landmark discovery, researchers using NASA’s Imaging X-ray Polarimetry Explorer (IXPE) have captured the first detailed view of the inner region where a dying white dwarf siphons material from a close stellar companion. This “vampire star” scenario, where a compact remnant…

Scientists unveil first look at a ‘vampire star’ feeding on its victim
Introduction: A cosmic vampire’s feast under X-ray eyes Astronomers have captured the first detailed view of a so-called “vampire star” system, where a dying white dwarf is siphoning material from a nearby companion. Using NASA’s Imaging X-ray Polarimetry Explorer (IXPE), researchers peered into the enigmatic inner region around the dead star, gaining fresh insights into…

Scientists See the Innermost Region of a White Dwarf Binary for the First Time
Unveiling a Rare Cosmic Dance About 200 light-years from Earth, a binary star system is offering scientists a rare, close look at the innermost region where a white dwarf and a companion star engage in a complex gravitational and magnetic ballet. The dead star, a dense white dwarf, siphons material from its larger partner, forming…

First Glimpse Inside a White Dwarf Binary’s Innermost Region
Unveiling a Cosmic Dance: The Innermost Region of a White Dwarf Binary About 200 light-years from Earth, a dramatic celestial pairing is offering scientists a rare glimpse into the extreme physics at the heart of a white dwarf binary. In this system, a dense, magnetized white dwarf siphons material from a larger companion star, creating…

Young Rogue Planet Cha 1107-7626 Reveals Star-Like Growth in the Darkness
Introduction: A rogue planet in the act In a striking turn for planetary science, a young rogue planet named Cha 1107-7626 is being observed during an extraordinary growth phase. Unlike Earth, which orbits the Sun, this free-floating world drifts through interstellar space without a host star. Yet Cha 1107-7626 appears to be forming much like…

SA 1107-7626: The Ultra-Fast Growing Planet That Redefines Exoplanet Theory
Disclaimer: This article describes a fictional scenario created to explore ideas about planet formation and exoplanet science. Overview: A Planet That Grows Without a Sun In a distant corner of a star-forming region, scientists describe a young, isolated planet named SA 1107-7626. Unlike Earth, Mars, or any world that orbits a star, SA 1107-7626 appears…

Rogue Planet Growth: Explosive Accretion in Space
The extraordinary finding A free-floating, or rogue, planet named Cha 1107-7626 is undergoing an immense growth spurt, pulling in gas and dust from its surrounding disk at roughly six billion metric tons per second. Scientists say this is the highest accretion rate ever measured for a planetary-mass object. The discovery, published in The Astrophysical Journal…

Rogue Planet Accretion Surges Explosively in Space
An international team of astronomers has documented an explosive growth phase in a rogue planet, Cha 1107-7626, a world that wanders interstellar space, unbound to any star. The object is accumulating gas and dust from a surrounding disk at a rate of six billion tonnes per second, the highest accretion rate ever recorded for an…

Rogue Planet Accretion: Explosive Growth Revealed in Space
Rogue Planet Accretion: An Unprecedented Growth Spurt Astronomers have identified an enormous burst of growth in a wandering planet, a rogue world that drifts through interstellar space without a parent star. The object, Cha 1107-7626, is accumulating gas and dust at a staggering rate of about six billion tons per second — the highest accretion…
