Answer:
For the first blank ; low
For the second blank ;high
Explanation:
When a low-mass star leaves the main sequence, it becomes a red giant before creating a planetary nebula and becoming a white dwarf.
When a high-mass star leaves the main sequence, it becomes a red super-giant before creating a supernova and becoming either a neutron star or black hole.
Answer: "Low mass star" and 'High mass star"
Explanation: A low mass star is one whose mass is less than half of the sun's entire mass. Here, the size is very small, temperature is very much cold and exist for a quite long period of time. It eventually dies out becoming a white dwarf, after exiting the main sequence.
A high mass star is the one whose mass is thrice more than the sun's entire mass. Here, the size is very big, temperature is significantly high and exist for a shorter period of time. It subsequently becomes a reddish colored enormous star and dies out forming a black hole or it could form a neutron star, after coming out of the main sequence.
