"Astronomers Uncover Ancient 'Old Smokers' and Erupting Protostars in the Milky Way"

Astronomers using the Visible and Infrared Survey Telescope (VISTA) have discovered 32 erupting protostars, experiencing rapid brightness increases within the disk of matter surrounding them, potentially affecting planet formation. Additionally, a new type of red giant star, known as "old smokers," has been found in the center of our galaxy, casting off clouds of dust that temporarily obscure the star and then re-brighten, potentially changing our understanding of heavy element release into the galaxy.

"Unveiling Ancient 'Old Smokers' and 'Screaming' Newborn Stars in the Milky Way"

Astronomers have discovered a new category of ancient giant red stars, dubbed "old smokers," as well as violently erupting newborn protostars in the Milky Way's heart through a 10-year survey with the VISTA telescope. The team found 32 erupting protostars and 21 "old smokers," which are red stars that suddenly emit clouds of smoke after sitting quietly for decades. These discoveries could provide insights into the distribution of heavy elements in the cosmos and the formation of stars and planets.

"Discovery of 'Old Smokers': Ancient Giant Stars Unveiled in the Milky Way"

Astronomers have discovered hidden stars, including a new type of elderly giant nicknamed "old smokers," at the heart of the Milky Way galaxy, using infrared light to see through the dust and gas that obscures them in visible light. The team also found rarely-seen newborn stars, known as protostars, undergoing extreme outbursts, shedding light on the formation of new solar systems. Additionally, they detected a new type of red giant star that remains dim and red for years before puffing out clouds of smoke, challenging previous understanding of stellar matter ejection and the distribution of heavy elements in the galaxy.
