How is an X-ray burst similar to nova?
How is an X-ray burst (in an X-ray binary system) similar to a nova? Both result in the complete destruction of their host stars. Both are thought to involve fusion of hydrogen into helium. Both typically recur every few hours to every few days.
What is the difference between a nova and an X-ray burster each one of the following answers is correct except one which one is the exception quizlet?
Each one of the following answers is correct except one. Which one is the exception? A nova involves stars in a close binary system, whereas an X-ray burster involves an individual star not in a binary system. The star that loses matter to a companion in a mass transfer binary system has its rate of evolution decrease.
What is a nova describe the process that creates a nova and what a nova looks like quizlet?
A nova is when a white dwarf gains back enough hydrogen to start fusion again and become a star. The flash causes a bright light flash that lasts few weeks.
What causes an X-ray burster to form?
For an X-ray burst, the compact object is a neutron star which accretes a surface layer of helium that undergoes explosive burning to produce the outburst. For recurrent novae, the compact object is a white dwarf which accretes a surface layer of hydrogen that undergoes explosive burning to produce the outburst.
Which of the following is not true about the differences between novae and supernovae?
Which of the following is not true about differences between novae and supernovae? Supernovae eject gas into space but novae do not. Will our Sun ever undergo a white dwarf supernova explosion?
What is this nova?
A nova (plural novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently “new” star, that slowly fades over several weeks or many months. Causes of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars.
What is the main observational difference between a Type I and a Type II supernova quizlet?
What are the observational differences between Type I and Type II supernovae? A type 1 Supernova has a light curve similar to that of a nova and they are hydrogen poor. A type 2 Supernova has a light curve with a plateau and they are hydrogen rich.
What is actually located at the event horizon of a black hole to define this entity?
A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can’t get out. Two main classes of black holes have been extensively observed.
What is nova describe the process that creates a nova and what does it looks like?
A nova occurs when the white dwarf, which is the dense core of a once-normal star, “steals” gas from its nearby companion star. When enough gas builts up on the surface of the white dwarf it triggers an explosion. For a brief time, the system can shine up to a million times brighter than normal.
What does a nova look like?
What is true about SN1987A see the following image )?
What is true about SN1987A (see the following image)? All choices are true. Neutrinos were detected before the visible blast. It was a supernova seen in the Large Magellanic Cloud.
What evidence can you cite that pulsars are neutron stars?
What evidence can you cite that pulsars are neutron stars? Only neutron stars are small enough to produces such short pulse lengths. not all of the sun’s mass is inside its schwarzchild radius. the observation of binart X-ray sources with mass greater than 3 masses.
