Concept explainers
The similarities and differences between neutron stars and white dwarfs.
![Check Mark](/static/check-mark.png)
Answer to Problem 1RQ
Both objects are similar in its birth, death, density and differed by the particles which oppose its gravity.
Explanation of Solution
Both the Neutron stars and White dwarfs are produced as a result of dying stars. The two are the end phases of an evolution of a star. They will gradually
As similarities mentioned above, the difference between the two is the particles responsible for balancing the inward gravitational force. For neutron stars, neutrons are responsible for creating an outward force which counteracts the gravity. In case of White dwarfs, it is electrons.
Therefore, both the objects are similar in its birth, death, density and differed by the particles which oppose its gravity.

Where would you expect to find Type I supernovae, which involve the explosions of white dwarfs?arrow_forwardHow do the two types of supernovae discussed in this chapter differ? What kind of star gives rise to each type?arrow_forward

- How would the spectra of a type II supernova be different from a type Ia supernova? Hint: Consider the characteristics of the objects that are their source.arrow_forwardApart from the masses, how are binary systems with a neutron star different from binary systems with a white dwarf?arrow_forwardHow would a white dwarf that formed from a star that had an initial mass of 1 MSunbe different from a white dwarf that formed from a star that had an initial mass of 9 MSun?arrow_forward
- Would you be more likely to observe a type II supernova (the explosion of a massive star) in a globular cluster or in an open cluster? Why?arrow_forwardLook elsewhere in this book for necessary data, and indicate what the final stage of evolution-white dwarf, neutron star, or black hole-will be for each of these kinds of stars. A. Spectral type-O main-sequence star B. Spectral type-B main-sequence star C. Spectral type-A main-sequence star D. Spectral type-G main-sequence star E. Spectral type-M main-sequence stararrow_forwardHow much would you weigh if you were suddenly transported to the white dwarf Sirius B? You may use your own weight (or if don’t want to own up to what it is, assume you weigh 70 kg or 150 lb). In this case, assume that the companion to Sirius has a mass equal to that of the Sun and a radius equal to that of Earth. Remember Newton’s law of gravity: F=GM1M2/R2 and that your weight is proportional to the force that you feel. What kind of star should you travel to if you want to lose weight (and not gain it)?arrow_forward
