... Our Galaxy . ... Stars . ... We all love bright and showy spiral galaxies! So much so, that we tend to overlook the elliptical galaxies which make up about 30% of the galaxies out there. Smaller than spiral galaxies, elliptical galaxies may be full of stellar living fossils, surviving virtually unchanged from an older cosmic era. ... Elliptical galaxies are smaller than spiral galaxies, roughly spherical and full of old stars. ... We know that galaxies interact and even collide. ...

NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...

Nonlinear tides in giant planets Adrian Barker DAMTP, University of Cambridge (formerly at CIERA, Northwestern) With: C. Baruteau, B Favier, P Fischer, Y Lithwick, G Ogilvie Introduction Motivation · Shortest period hot Jupiters (M ~ MJup, P < 10 d) have preferentially circular orbits => thought to be explained by tidal dissipation inside the planet (e.g. Rasio et al,1996) If so, what mechanisms are responsible? ... Linear theory contains uncertainties (e.g. Zahn, Ogilvie, Papaloizou, Ivanov, Wu). ...

Uniform Circular Motion . Kepler's First Law: All planets move about the sun in an elliptical orbit with the sun at one foci. ... In the above P is the orbital period measured in years and A is the semi-major axis measured in units of AU (the distance from the earth to the Sun). ... The discovery of retrograde motion in the orbit of mars was a serious challenge to the standard geocentric cosmology which demanded that all the planets orbit the earth in the same direction. ...
