What do black holes form?
Black holes are sort of the final stage of stellar evolution; they don't form much else. Two black holes may merge to form a larger one, and after a very, very long time, they will evaporate.
The remaining core of a planetary nebula is called a?
The remaining core of a planetary nebula is called a white dwarf. This stellar remnant is composed mainly of carbon and oxygen and represents the final stage in the evolution of stars that were once similar in size to our Sun. As the outer layers of the star are expelled, the white dwarf gradually cools and dims over time.

Who discovered Evolution of stars?
The concept of stellar evolution was significantly advanced by the work of astrophysicists such as Sir William Herschel in the 18th century, but it was further developed in the 20th century by scientists like Subrahmanyan Chandrasekhar, who studied the life cycles of stars and the processes leading to phenomena like supernovae and black holes. The Hertzsprung-Russell diagram, created by Ejnar Hertzsprung and Henry Norris Russell, also played a crucial role in understanding how stars evolve over time based on their luminosity and temperature. Overall, the discovery of stellar evolution is attributed to the contributions of many scientists over time.
Is there a code to get grovyle to reappear in Pokemon explorers of time?
no just recruit 3 treecko's from mystery jungle 1 for each evolution stage..that's what i do it saves time that way..veronica
How long does it take an M-type star to reach the main sequence compared to a star like your sun?
The main-sequence of stellar evolution is followed by stellar ignition of a protostar (Assuming it's not a failed ignition). Stars are not classified in the Hertzprung-Russel diagram's main sequence until stellar ignition has been initiated. Additionally, the length of time it may take for a protostar to reach T Tauri and initiate stellar ignition depends on the mass of the protostar. The heavier, the quicker. The lighter, the slower. For an example, it takes about 1,000 years for a 1 solar mass protostar to initiate stellar ignition. So since stars cannot be classified in the main-sequence before they initiate stellar ignition, you can't know the difference in time. since you won't know what will be what class star. The main reason is because the mass of the protostar fluctuates as it accretes matter, becomes T Tauri type and begins stellar ignition. At stellar ignition, a T Tauri star can lose up to 50% of its original mass.
What is a change of a species over time called?
Evolution is a change in species over time.
The second time you face your rival at the elite 4 he has a tyranitor how do you get one in Pokemon leaf green?
you must catch a larvitar on island seven. tyranitar is its 3rd evolution stage
What effect does generation time have on evolution?
A long generation time makes for a slow evolution rate, and a short generation time makes for a fast evolution rate.
Who discovered the life cycle of a star?
The life cycle of a star was not discovered by a single individual, but rather developed through the contributions of many astronomers and astrophysicists over time. Key figures include Sir Arthur Eddington in the early 20th century, who explored stellar structure and energy production, and later scientists like Fred Hoyle and George Gamow, who contributed to our understanding of nucleosynthesis and stellar evolution. The comprehensive model of stellar life cycles emerged as a result of advancements in observational astronomy and theoretical physics.
What were Iraq's excuses for the war?
Iraq's government (Saddam's regime) was replaced by the US in 2003. They are experiencing a new country's "developement stage" at this time; meaning, a need for law, order, and stability for their "new" government.
