... Bad Astronomy . ... Bitesize Astronomy . ... You can be very general (``on Earth'', or ``150 million kilometers from the Sun''), or very specific. ... As part of my daylife work, I was assigned the task to find out just where the Earth is at a given time. We need this because we are observing a target that pulses, and to time the pulses we need to know just where the Earth is in relation to the Sun. ... To understand the delay, we need a very good position for the Earth. ... 2008 Phil Plait. ...

... The goal of this course is to introduce some -- very interesting -- basic examples and notions of combinatorial game theory, following the book "How to win your mathematical games", by Berlekamp, Conway and Guy. ... So, for every game there is a winning strategy, and to find one one can use the well-known idea of winning/losing positions. ... Temperature theory. We will see the limits of the association of numbers and games: some positions can not be associated to a single real number! ...

PULSE PROFILES AND CYCLOTRON LINE ENERGY DEPENDENCE ON X-RAY PULSARS LUMINOSITY S. Tsygankov, A. Lutovinov, E. Churazov, and R. Sunyaev Space Research Institute, Profsoyuznaya str. ... CYCLOTRON LINE ENERGY 2.1. ... We concentrate on the luminosity and energy dependence of the pulse profile and the variations of the cyclotron line energy. In V0332+53 the line energy changes nearly linearly with the source luminosity, while in 4U0115+63 its behavior is more complicated. ...

... astro-ph . ... Statistical Characterization of the Chandra Source Catalog . ... The first release of the Chandra Source Catalog (CSC) contains ~95,000 X-ray sources in a total area of ~0.75% of the entire sky, using data from ~3,900 separate ACIS observations of a multitude of different types of X-ray sources. ... In addition to these traditional catalog elements, for each X-ray source the CSC includes an extensive set of file-based data products that can be manipulated interactively. ...
