Dwarf Star

An undetected intermediate-mass black hole lurking in a dwarf galaxy revealed itself to astronomers when it devoured an unlucky star that got too close.

Scientists are finding all sorts of weird worlds. They've now discovered a gas giant planet with the density of a marshmallow orbiting a cool red dwarf star located 580 light years from Earth. The planet, identified as TOI-3757 b, is the "fluffiest".

The study was published in the journal Astronomy & Astrophysics.

A team of astronomers at the University of Surrey recently found an extremely faint, dwarf galaxy which, they believe, is one of the first galaxies packed with a very old star. The galaxy, monikered as Pegasus V, is located in the vicinity of the Andromeda galaxy. The “fossil” galaxy that the team discovered has a high concentration of old star...

A research team including astronomers from the US, India and France have studied the formation of new stars beyond the visible boundaries. The team is yet to understand how the dwarf galaxies of the past have evolved into the ones in the present day. The team includes Indian scholar Anshuman Borgohain from Tezpur University.

A first of its kind study has found new stars forming beyond the visible boundaries about 1.5 to 3.9 billion light years away from the Earth, according to an article by a research scholar of Tezpur University.

A team of astronomers from the Yunnan Observatories (YAO) of the Chinese Academy of Sciences and the Australian National University have jointly discovered a binary system that is ejecting a common envelope. The scientists have managed to observe a common envelope evolution, which has long been thought to be a key step in binary star system formati...

Astronomers have observed a star that not only survived a stellar explosion called a supernova, but emerged from it brighter than before the blast. This white dwarf is gravitationally locked in orbit with another star — a pairing called a binary system.

Astronomers have made an exciting new discovery, identifying a newborn pulsar that may possibly be only 14 years old. Scientists were finally able to observe the pulsar after the dense debris and bright energy emissions from the supernova explosion that created the pulsar finally thinned enough.

The discovery was made by analysing archival data from NASA's Hubble Telescope and other observatories of the American space agency. Termed cosmic cannibalism, the observation helped shed light on the violent nature of the evolved planetary system and can help astronomers in understanding the makeup of newly forming systems.

Researchers are hopeful that an extraterrestrial stone found in the Egyptian desert could help shed some light on these spectacular events. The stone is named Hypatia. The experts have a hypothesis that the Hypatia stone originated with a star – a red giant star collapsed into a white dwarf star, which eventually “ate” the other star.

A team of researchers have found that a quadruple star system – known as HD 74438 – could represent a new channel by which thermonuclear supernova explosions can occur in the universe. In their study published in the journal Nature Astronomy, they have shown that the gravitational effects of the outer binary system are changing the orbits of th...

The mysterious radio signal is located roughly 4,000 light-years away from Earth

Astronomers using the Chandra X-ray Observatory have spotted a white dwarf consuming the debris of planets that once orbited it.

A recent research based on Hubble Space Telescope findings showed that black holes could go against their all-absorbing nature at times and may aid creation. The research showed a supermassive black hole at the centre of a dwarf galaxy, some 30 million light-years away, creating stars rather than swallowing it.
