Black holes Notes
... Summary of Chapter 22 (cont.) • A distant observer would see an object entering black hole subject to extreme gravitational redshift and time dilation. • Material approaching a black hole will emit strong Xrays. • A few such X-ray sources have been found and are black-hole candidates. ...

Today in Astronomy 102: observations of stellar
... High-energy light (X/ rays): gives promising, but not completely unambiguous, detections of black holes. Orbital motion of companion stars • Orbit size, speed plus Newton’s laws can be used to work out the mass of a visibly-dim (but perhaps X-ray bright) companion. If it’s more than 2 M … • We ...

Answers to Physics 176 One-Minute Questionnaires Lecture date: January 27, 2011
... Can you explain a little more why we can ignore the rotation along the axis of a diatomic molecule? You can find a good discussion of this in the article “Specific heats and the equipartition law in introductory textbooks” by C. Gearhart, American Journal of Physics, Volume 64, pages 995-1000 (1996 ...
