... M ercury is the closest planet to the Sun and the eighth largest. ... Heraclitus even believed that Mercury and Venus orbit the Sun, not the Earth. ... The perihelion of its orbit precesses around the Sun at a very slow rate. 19th century astronomers made very careful observations of Mercury's orbital parameters but could not adequately explain them using Newtonian mechanics. ... Actually Earth's density is due in part to gravitational compression; if not for this, Mercury would be denser than Earth...

... Astrophysics Group . ... AMI Science . ... Observations of galaxy clusters are central to the AMI science programme. The AMI Small Array is used to observe already-known clusters with high-sensitivity and resolution, allowing us to extract detailed information about individual clusters and to build up statistics about the cluster population. ... Observing galaxy clusters at 15 GHz is tricky because of the contamination from foreground radio sources, which is where the Large Array comes in! ...

... Bad Astronomy . ... Bitesize Astronomy . ... For example, I have recently become interested in very low mass stars; stars with less than 15% or so the mass of the Sun. ... The painting is of an extremely low mass star called Gliese 229B or Gl229B for short. Gl229B is what we call a brown dwarf; a star with such a low mass that it cannot even fuse hydrogen into helium in its core. Gl229B orbits a more massive, but still very low mass star, called (you guessed it!) ... 2008 Phil Plait. ...

The integrated H I line flux, the characteristic widths of 21 cm line profile W 50 and W 20 (for a Hanning smoothing of 10.6 km s -1 ), and the derived H I mass for HS 0822+3542 are presented in Table 1 . The small H I mass 2.4 of this galaxy is consistent with its low optical luminosity. ... A rough estimation can be made also on the dynamical mass of HS 0822+3542. ...

Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

... The nebular spectra of SNeIa can be used to determine the mass, density, and distribution of the SN ejecta, and the distance and reddening to the SN. Synthetic spectra can very rapidly be computed in NLTE and compared to the observed ones. Given the relatively large number of parameters, it is convenient to explore the parameter space in an automated form. The nebular spectrum synthesis code can be run in parallel on a workstation cluster. ...
