On leaving the planetarium, turn around and look northwards over the roof of the building. To your right is a group of stars like the outline of a saucepan standing up on it’s handle. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The top two stars are called the Pointers. Check with binoculars. Not all stars are white. The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris.

  • The Hertzsprung - Russell Diagram Today You Will Be Making the Hertzsprung - Russell Diagram
    Name: ___________________________________ The Hertzsprung - Russell diagram Today you will be making the Hertzsprung - Russell diagram. The H-R diagram allows astronomers to classify stars into groups. The two axes for this graph will be temperature and magnitude. When we refer to temperature, we are talking about the surface of the star. The surface temperature is much cooler. For example, our sun’s surface temperature is ~5,500K to 6,000 K. Kelvin is a temperature scale very similar to Celsius. Absolute magnitude is a measurement of how bright a star really is. This is determined by its size and by its temperature. Even though it might look bright in our sky, we try to compare all stars as if we were standing the exact same distance away from each one. This magnitude value is stated by calculating how bright the object would shine at a fixed distance away in space, ~32.6 light years (10 parsecs for those wanting another measurement to think about).

General Properties Young stars are associated with molecular clouds. Observations are affected by extinction, which decreases with increasing wavelength. Loosely speaking, we can distinguish two types: Embedded stars - seen only at NIR or longer wavelengths, usually presumed to be very young Revealed stars - seen at optical wavelengths or shorter, usually presumed to be older What makes young stars particularly interesting is Circumstellar gas and dust – both flowing in as well as out, e.g., jets, winds, & disks.

  • The X-Ray Puzzle of the L1551 IRS 5 Jet
    A&A 530, A123 (2011) Astronomy DOI: 10.1051/0004-6361/201016305 & c ESO 2011 Astrophysics The X-ray puzzle of the L1551 IRS 5 jet P. C. Schneider1, H. M. Günther2, and J. H. M. M. Schmitt1 1 Hamburger Sternwarte, Gojenbergsweg 112, 21029 Hamburg, Germany e-mail: [cschneider;jschmitt]@hs.uni-hamburg.de 2 Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA, USA e-mail: [email protected] Received 13 December 2010 / Accepted 18 April 2011 ABSTRACT Protostars are actively accreting matter and they drive spectacular, dynamic outflows, which evolve on timescales of years. X-ray emission from these jets has been detected only in a few cases and little is known about its time evolution. We present a new Chandra observation of L1551 IRS 5’s jet in the context of all available X-ray data of this object. Specifically, we perform a spatially resolved spectral analysis of the X-ray emission and find that (a) the total X-ray luminosity is constant over almost one decade, (b) the majority of the X-rays appear to be always located close to the driving source, (c) there is a clear trend in the photon energy as a function of the distance to the driving source indicating that the plasma is cooler at larger distances and (d) the X-ray emission is located in a small volume which is unresolved perpendicular to the jet axis by Chandra. A comparison of our X-ray data of the L1551 IRS 5 jet both with models as well as X-ray observations of other protostellar jets shows that a base/standing shock is a likely and plausible explanation for the apparent constancy of the observed X-ray emission.
