Consider the image above of the Cassiopeia A (Cas A) supernova remnant. The supernova explosion that caused this remnant was observed on earth about 300 years ago. It is about 3000 pc away. Since that time, the shockwave from the supernova has expanded to form the roughly spherical cloud pictured above. From the center point to the edge of the cloud is about 3 pc. Compute the angular diameter of the Cas A supernova remnant as viewed from Earth. Express your answer in arcminutes.

The H-R diagram is the most important graph in astronomy. One of the reasons that this graph is so powerful is the number of different kinds of data it shows. Most graphs show two types of data. The H-R diagram shows seven. Can you name these 7 types of information about stars that appear on the H-R diagram?
Which statement is most logical? a Once gravity overcomes thermal pressure, nebulae cloud turns into molecular cloud. If it is cold and dense enough, molecular cloud might turn into protostar. b If gravity is stronger than thermal pressure, nebulae cloud contracts into molecular cloud. If it is cold and dense enough, molecular cloud might turn into protostar. c If a molecular cloud is cold and dense enough, it turns into a protostar. Once gravity overcomes thermal pressure, protostar might become molecular cloud. d If a nebulae cloud is cold and dense enough, it turns into molecular cloud. If gravity is stronger than thermal pressure, molecular cloud might become protostar.
This star has a mass of 3.3 MSun. What is the main sequence lifetime of this star? You may assume that the lifetime of the sun is 1010 yr.
One way to calculate the radius of a star is to use its luminosity and temperature and assume that the star radiates approximately like a blackbody. Astronomers have measured the characteristics of central stars of planetary nebulae and have found that a typical central star is 16 times as luminous and 20 times as hot (about 110,000 K) as the Sun. Find the radius in terms of the Sun’s. How does this radius compare with that of a typical white dwarf?
Choose the correct statements from the following list referring to white dwarfs. (Give ALL correct answers, i.e. B, AB, BCD...) A) Stars with a mass like the Sun will end up as a white dwarf star. B) White dwarfs with mass greater than 1.4 times the Sun's mass cannot exist. C) White dwarfs are less dense than red giants. D) The pressure that balances gravity in a white dwarf is called degenerate electron pressure. E) White dwarfs cool slowly because they are small and eventually fade-out to become black dwarfs. F) The power source of white dwarfs is left-over heat. G) White dwarfs are the coolest main sequence stars.
Place the following events in the formation of stars in the proper chronological sequence, with the oldest first and the youngest last. w. the gas and dust in the nebula flatten to a disk shape due to gravity and a steadily increasing rate of angular rotation x. a star emerges when the mass is great enough and the temperature is high enough to trigger thermonuclear fusion in the core y. the rotation of the nebular cloud increases as gas and dust concentrates by gravity within the growing protostar in the center z. some force, perhaps from a nearby supernova, imparts a rotation to a nebular cloud y, then z, then w, then x z, then y, then w, then x w, then y, then z, then x z, then x, then w, then y x, then z, then y, then w MacBook Air on .H.
