Both, a low mass Star and a High mass Star will Start off with fusing hydrogen into Helium, though a high mass Star will burn it faster because of increased pressure and temperature in the core. A second
difference is the ability to create heavier elements
. … This is called a Neutron Star and has a size of rougly 20km.
What is a high mass star?
High-mass stars are
very luminous and short lived
. They forge heavy elements in their cores, explode as supernovas, and expel these elements into space. Apart from hydrogen and helium, most of the elements in the universe, including those comprising Earth and everything on it, came from these stars.
What is the difference between a high mass star and a low mass star?
High mass stars use up their hydrogen fuel very rapidly and consequently have short lives. High mass stars pass through a Red Supergiant stage before dying catastrophically in supernovae explosions. … Low mass stars use up their hydrogen fuel
very slowly
and consequently have long lives.
What do low mass stars and high mass stars have in common?
Low mass stars and high mass stars share similarities and differences. One of the similarities is they both start the same way, with a huge collection of gases, primarily
hydrogen and helium
. Another similarity would be the way they generate their energy, through a process known as nuclear fusion.
What is one way in which high mass stars differ from low mass stars quizlet?
Terms in this set (36)
High-mass stars differ from low-mass stars in
that they burn helium to carbon when on the main sequence
. Fusion reactions that create chemical elements heavier than oxygen require energy input; thus, these reactions cannot provide a star with power.
What is the most massive star in the universe?
R136a1
is the most massive known star in the universe, but it is far from unique. A 2018 study of the Tarantula Nebula, also called 30 Doradus or 30 Dor, revealed that R136a1 is not alone; the nebula hosts several other stars with the greatest masses yet detected.
What happens in a high mass star?
High mass stars go through a similar process to low mass stars in the beginning, except that it all happens much faster. They have a
hydrogen fusion core
, but much of the hydrogen fusion happens via the CNO cycle. … If the star is massive enough, the neutron star will collapse further and form a black hole.
What comes after a high mass star?
A massive star will undergo
a supernova explosion
. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different.
What are 2 characteristics of high mass stars?
- Very high-core temperatures.
- Crushing stellar-core pressures.
- Very big and very bright,
- Ends its stellar life with a bang.
What is the lifespan of a high mass star?
A star with a mass 25 times that of the Sun will live for
about 2.5 million years
.
What is the difference between a low mass and a high mass?
A High Mass is scheduled for
every Sunday
, each Holy Day of Obligation and certain major holy days. Low Masses are generally offered during the week and on Saturdays, especially when only a small group of people are expected to attend.
Do high mass stars live longer than low mass stars?
The fuel is hydrogen atoms and the number of hydrogen atoms is greater in high mass stars than it is in lower mass stars. Thus, the higher the mass of the star, the longer its lifetime can be. … Lower mass stars live
longer than
the sun. Higher mass stars live shorter than the sun.
What is the lowest mass star?
The red dwarf stars
are considered the smallest stars known, and representative of the smallest star possible. Brown dwarfs are not massive enough to build up the pressure in the central regions to allow nuclear fusion of hydrogen into helium.
Why do stars of lesser mass live longer than stars of larger mass?
Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions,
their rate of consuming their fuel is very much greater
.
What would happen if mass were continually added to a 2.8 solar mass neutron star?
What would happen if mass were continually added to a 2-M⦿ neutron star?
The star’s radius would increase
. The star would eventually become a black hole.
Why do stars of lesser mass live longer than stars of larger mass quizlet?
Stars that begin their lives with the most mass live longer than less massive stars
because it takes them a lot longer to use up their hydrogen fuel
. No, more massive stars are much more luminous than low mass stars and use up their hydrogen faster, even though they have more of it.
