The Mysterious Millinovas: A New Era in Astronomy
Astronomers have made a remarkable breakthrough with the discovery of millinovas, an entirely new category of cosmic explosions that outshine the Sun by a staggering 100 times. This exciting find arose from data analysis conducted on satellite galaxies of the Milky Way, revealing unique traits that distinguish millinovas from previously known stellar events, such as novae and supernovae. Researchers believe these explosions occur within binary star systems where a white dwarf absorbs material from a subgiant star, resulting in violent outbursts of heat and X-ray radiation.
Published in the Astrophysical Journal Letters, the study spearheaded by Przemek Mróz at the University of Warsaw sheds light on the intricate interactions between stars. Millinovas are characterized by their distinctively symmetrical, triangle-shaped outbursts, offering new perspectives on cosmic evolution and stellar behavior.
The discovery unraveled when the team pored over 20 years of data from the Optical Gravitational Lensing Experiment (OGLE) while hunting for primordial black holes. Instead, they stumbled upon 28 instances of millinovas located in the Large and Small Magellanic Clouds, with one notably intense event, OGLE-mNOVA-11, showing extreme temperatures exceeding 1 million degrees Fahrenheit.
Within this newly defined class of transient X-ray sources, millinovas represent a fascinating area for future research, promising to advance our understanding of the universe’s dynamic nature and the life cycles of stars.
