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 Ї 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). ...

... Data . AAS 221 . AAS 219 . ... The first thing to note is that Twitter does not guarantee to return all matching Tweets, whatever method is used (unless you have direct access to their "fire hose", which I don't). ... This should result in the same results as my REST-based search (method 2), since the volume of Tweets was probably not enough to cause this site to miss Tweets based on their collection strategy . ... A search for the tag #aas219 (case insensitive) using the Twitter REST API . ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

. A cartoon of the two giant stars in the binary system. The polarity of the star's surface magnetic field, north or south, is indicated by red and blue, respectively. Yellow lines indicate the magnetic field lines running from the stellar surfaces. Visualisation courtesy of Volkmar Holzwarth, KIS, Freiburg.

... If the Earth is round, the Sun must be north of the equator in northern summer, and south of the equator in northern winter. ...

If the rotation axis of the Earth is tilted with respect to its orbit, the equator bobs back and forth, causing the Sun to be north for half the year, and south for the other half (see figure 9 ). ...

TclActor is a set of classes that allow one to write an actor for the 3.5m control system. ... Thus, to the extent that the underlying hardware controllers support it, an actor based on TclActor can execute multiple commands at the same time. ... Commands must be in the following format: [cmdId [msgId]] [verb [arguments]] where: . ... The device code tends to fall into several categories: code to support executing commands, code to handle replies and code to represent the internal state of the device. ...
