What will be an ideal response? Question 2 Some young star clusters contain large numbers of T Tauri stars. a. True b. False Indicate whether the statement is true or false Question 3 Compare and contrast the properties of disk and halo stars. What will be an ideal response? Question 4 ___________ associations and ___________ associations are groups of stars born together but not gravitationally bound to one another. Fill in the blank(s) with correct word Question 5 Discuss how astronomers know that our galaxy contains spiral arms in its disk. What will be an ideal response?

Post by: bvillan1 on Mar 19, 2018 Peculiar features such as threads, the Arc, and the Snake may be gas trapped in magnetic fields. TRUE Most of the stars in the disk are middle- to lower-main-sequence stars like the Sun, a few are red giants and white dwarfs, and fewer still are brilliant blue O and B stars. Those hot, massive stars are rare, but they are so luminous that they provide much of the light from the disk. Halo stars are old, cool, lower-main-sequence stars, red giants, and white dwarfs. T, OB OB, T Radio astronomers use the strong spectral line emission from carbon monoxide (CO) to map the location of giant molecular clouds in the plane of the galaxy. Giant molecular clouds are sites of active star formation. If you point a radio telescope at a section of the Milky Way, you will receive a combination of signals from gas clouds in the direction you are looking that lie at various distances across the galaxy. Signals from those different clouds can be separated by measuring the Doppler shifts of their spectral lines. Astronomers then use a simple model of orbital velocities at different distances from the center of the galaxy in order to untangle the observations and locate the individual clouds. Maps constructed from such observations reveal that the giant molecular clouds, like O and B stars, are located along segments of spiral arms.
