How can you explain the Algol paradox?
In some binary systems, the less-massive star has become a giant, while the more-massive star is still on the main sequence. If higher-mass stars evolve faster than lower-mass stars, how do the lower-mass stars in such binaries manage to leave the main sequence first? This is called the Algol paradox, after the binary system Algol.
What are hypervelocity stars?
Hypervelocity stars (HVS) are a unique class of stars which are defined by their extreme velocities (around 1,000 km/s). In fact, they are moving fast enough to be gravitationally unbound to the Galaxy. They were first predicted in 1998 and are thought to be a result of three-body interactions between a binary star pair and a massive black hole (MBH) that resides in the galactic center. The first HVS was discovered in 2005 and there are now about 20 known HVS.
What are the three main categories of dead stars?
The first category is the white dwarf these are the stars that our Sun will become. The second category are the more massive stars that will collapse down to neutron stars. The final category is a black hole.
What is the likely reason that you cannot find any examples of the first generation stars?
First generation stars are believed to have formed shortly after the Big Bang, making them extremely old and therefore difficult to observe. Additionally, these stars are thought to have been massive and short-lived, likely turning into black holes or exploding as supernovae before leaving behind any detectable remnants.
The first stars formed in clouds of?
The first stars formed in clouds of predominantly hydrogen and helium gas. These clouds were massive and dense, collapsing under their own gravity to ignite nuclear fusion in their cores, marking the birth of the first generation of stars in the universe.
What is the first value in binary?
The first value in binary is 1
What is a star capella?
TheÊstar named Capella is the third brightest star in the Northern Hemisphere and is actually a grouping of four individual stars grouped in binary pairs. It was first discovered to be binary pairs in 1899.
What is the difference between 1st generation stars and 2nd generation stars?
1st generation stars, also known as Population III stars, formed shortly after the Big Bang and consisted mainly of hydrogen and helium. They are believed to have been massive and short-lived. 2nd generation stars, or Population II stars, formed from the remnants of 1st generation stars and contain heavier elements produced in their cores. They are typically older and less massive than 1st generation stars.
What may have been the first source of light in the early universe?
The remnants of the big bang initially. Then the first stars formed.
What were the first stars called?
The first stars are called population III stars as they were the first stars created - about 400 million years - after the big bang. They consisted of hydrogen and helium only (and maybe a small amount of lithium) and would have been massive. As such, their lifespan would only have been in the millions of years, rather than the billions of years for the current population I stars (Like our Sun). To date, no population III stars have been observed and thus have not been named.
Are all young main sequence stars blue?
No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.
What is the first known black hole?
The first black hole discovered is Cygnus X-1, which was identified in 1964 as a strong X-ray source in the constellation Cygnus. It is a binary system with a massive, invisible companion that is believed to be a black hole about 15 times the mass of the Sun.
