What happens if the mass of a white dwarf reaches the 1.4 solar mass limit?
The white dwarf (which is made mostly of carbon) suddenly detonates carbon fusion and this creates a white dwarf supernova explosion.
Is Sirius a low mass star?
It is, but at twice our suns mass, Sirius A is on the limit, of being an intimidate mass star. Sirius A will have a life cycle similar to that of our own star which is a low mass star, but burns hotter. Sirius B is a companion white dwarf star with a mass of around the same as our sun. Previously, it was thought to have been a star with a mass of around 5 times that of our sun, burning out more quickly than Sirius A.
What neutron star is smaller than white dwarfs are thought to be remnants of .?
A neutron star is the remnant of a star, which - at the end of its life, and AFTER possibly losing a lot of mass (for instance, in a supernova explosion) has a remaining mass that is greater than the so-called Chandrasekhar limit.
Is the Rigel star a high mass star or a low mass star?
High mass.
Is vega a low medium or high mass star?
Vega has about 2.1 times the mass of the Sun. That's a fairly large mass; but you'll have to choose where you set the limit between "medium-mass" and "high-mass"! It is definitely not "low-mass"; in general, low-mass stars, i.e. red dwarves, can't be seen with the naked eye, even if they are in our immediate neighborhood. (The very closest star after the Sun is Proxima Centauri, and it can't be seen with the naked eye.) The main definition of a high mass star is a star that can eventually explode as a supernova. For that the star needs to be around at least 8 times the Sun's mass. I would say Vega is best thought of as "medium mass".
Why is there a lower limit on the mass that a star may have?
It's because a gas cloud has to have a critical mass in order to generate enough temperature to start the nuclear processes that enable the star to radiate heat and light.
Is the sun a lower mass star or a higher mass star and which stage is it in?
The Sun is a medium mass star on the main sequence.
There is no limit to the mass with which a star can be born?
FALSE FALSE
Why is there a lower limit on the mass of a star?
A star must have at least a certain mass, the exact number depends on the star's composition, in order for gravity to be strong enough to sustain fusion of hydrogen-1 at the core. Bodies just under that mass are known as brown dwarfs, which have a mass somewhere between the largest gas giants and the smallest stars.
Why is there an upper limit to the mass of neutron stars?
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
An object forms with a mass of 0.017 Msun. Is it a star or planet?
The difference between a star and a planet with such a mass is kind of fuzzy. I would say it is a brown dwarf - a very small and dim star. The smallest known star is currently OGLE-TR-122b with a mass of 0.09 Msun. THey think the lower limit for a star to have fusion occur is about 0.08 Msun. So, an object with 0.017 Msun would be a planet.
What is the connection between chondro shekhor limit and black hole?
The Chandrasekhar limit describes the maximum stable mass of a highly compressed type of star called a white dwarf - a collapsed remnant of a star towards the end of its life cycle. This mass limit is about 1.44 times the mass of the sun; above this mass, gravitational force is calculated to overcome the outward pressure and thus precipitate further collapse, for example, into a neutron star. If the neutron star is of sufficient mass it may yet again collapse further, into more exotic states including possibly a black hole. Note that the mass limit of a neutron star (the Tollman-Oppenheimer-Volkoff limit) of around 3-4 solar masses is separate and distinct from the Chandrasekhar limit - you might say that the Chandrasekhar limit is just one of the mass limits along the stellar remnant's evolution into a black hole.
What happens if the mass of a white dwarf reaches the 1.4 solar mass limit?
The white dwarf (which is made mostly of carbon) suddenly detonates carbon fusion and this creates a white dwarf supernova explosion.
Is there a limit for the stars?
Yes, there are limits for stars - limits to lower and upper mass, longevity, size, etc. Given the mass of the universe a limit for the number of extant stars would also exist. During stellar collapse at end of a star's life there are some well-studied limits answering to degeneracy pressure, like the Chandresekhar limit, the Oppenheimer-Volkoff limit, etc., which prevent further collapse until a certain mass limit is exceeded (perhaps the last limit being quark degeneracy pressure before further collapse into a black hole). For further examination of a given limit, the limit in question would need to be identified.
Is Sirius a low mass star?
It is, but at twice our suns mass, Sirius A is on the limit, of being an intimidate mass star. Sirius A will have a life cycle similar to that of our own star which is a low mass star, but burns hotter. Sirius B is a companion white dwarf star with a mass of around the same as our sun. Previously, it was thought to have been a star with a mass of around 5 times that of our sun, burning out more quickly than Sirius A.
What is the Chandra analysis?
Hopefully you mean the Chandrasekhar Limit or Chandra Limit (Named after the Indian born Astrophysicist bearing that name) which states the maximum mass of a White Dwarf Star. If the Star exceeds this limit, then gravity will overcome pressure within the Star and it will collapse into a Neutron Star or Black Hole. See link for further information
What is the minimum mass a body can have and still considered a brown dwarf?
The lower mass limit is a subject of debate; it might be somewhere around 13 times the Jupiter mass.
