1 light-years (about 600 billion miles) of an O-type star are doomed to have their cocoons of dust and gas stripped away in just a few millions years, much faster than planets are able to form.
Many of these nascent systems will go on to develop planets, while others will have their planet-forming dust and gas blasted away by the fierce ultraviolet radiation emitted by massive O-type stars that lurk nearby.
It has a spectroscopic companion, an O-type star
, orbiting in 33 days.
1 light-year (about 600 billion miles) of an O-type star are doomed to have their cocoons of dust and gas stripped away in just a few millions years, much faster than planets are able to form.
A team of astronomers from Canada and the United States has used the Atacama Large Millimeter/submillimeter Array (ALMA) to study the often deadly relationship between highly luminous O-type stars and nearby protostars in the Orion Nebula.
The densest clumps will blossom into the cluster's biggest, most powerful stars, called O-type stars
, the formation of which has long puzzled scientists.
The tight grouping contains perhaps a few dozen very hot O-type stars
of various magnitudes.
Astronomers have detected dozens of young, bright O-type stars
in this ring, which suggests that hundreds of fainter Sun-like stars also exist there.
An international team has used the VLT to study what are known as O-type stars, which have very high temperature, mass and brightness.
By analysing the light coming from these targets in greater detail than before, the team discovered that 75 per cent of all O-type stars exist inside binary systems, a higher proportion than previously thought, and the first precise determination of this number.
They looked at what are known as O-type stars
, which have very high temperature, mass and brightness.
