What is a starburst space?
A starburst region is a region of space that is undergoing a large amount of star formation. For example, the Tarantula Nebula is a nebula in the Large Magellanic Cloud which has one of the highest star formation rates in the Local Group.
What is the defining characteristic of starburst galaxies?
What is the defining characteristic of starburst galaxies? They have a large number of young stars.
How are starburst galaxies formed?
The most popular theory is that a galaxy is put into a starburst phase when it makes a close encounter with another galaxy. The gravitational interaction sends shockwaves through giant clouds of gas, causing them to collapse and form star forming regions.
What is a starburst galaxy quizlet?
A starburst galaxy is a galaxy that is forming new stars at a very high rate.
What kind of galaxy is the starburst galaxy?
Luminous infrared galaxies (LIRGs). Ultra-luminous Infrared Galaxies (ULIRGs).
What is a starburst galaxy and what main features might we look for in detecting a starburst galaxy?
Starburst galaxies are galaxies where high rates of star formation has occurred very quickly. Nearly all types of galaxies can undergo starburst events if conditions are right. Astronomers know that starburst galaxies are often involved in mergers that mingle stars and gas.
How is a starburst galaxy likely to be formed quizlet?
How is a starburst galaxy likely to be formed? from a galactic merger.
What happens after a starburst?
After the supernova explosion, the ejected material expands and becomes a supernova remnant. These remnants interact with the surrounding environment within the starburst (the interstellar medium) and can be the site of naturally occurring masers.
What is a starburst galaxy and what does it indicate about galactic evolution?
The Antennae are undergoing a period of starburst brought on by the interaction of the two galaxies. Credit: AAO/David Malin. Starburst galaxies are galaxies that are observed to be forming stars at an unusually fast rate (about 103 times greater than in a normal galaxy).
What is special about starburst galaxies quizlet?
Why are starburst galaxies very bright in the infrared? Dust absorbs most of the light from the newly formed stars–starburst galaxies are very bright in the infrared. Quasi-stellar objects. The very brightest active galactic nuclei, which are huge amounts of radiation from their galactic center.
What are starburst galaxies made of?
A starburst galaxy is a galaxy undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy or the star formation rate observed in most other galaxies.
Are starburst galaxies irregular?
One type of irregular galaxy is called a “starburst galaxy.” Starburst galaxies shine brightly as many new stars are born in a short period of time. Irregular galaxies are usually found in groups or clusters, where collisions and near-misses between galaxies are common.
