Asteroseismology of Red Giant stars
N. J. Tarrant, W. J. Chaplin, Y. P. Elsworth +2
Sun-like oscillations, that is p-modes excited stochastically by convective noise, have now been observed in a number of Red Giant stars. Compared to those seen in the Sun, these m…
A Deep 150 MHz GMRT Survey in Eridanus
Samuel J. George, Ian R. Stevens
We present results of a 150 MHz survey of a field centered on Epsilon Eridani, undertaken with the Giant Metrewave Radio Telescope (GMRT). The survey covers an area with a diameter…
The period and amplitude changes of Polaris (alpha UMi) from 2003 to 2007 measured with SMEI
S. A. Spreckley, I. R. Stevens
We present an analysis of 4.5 years of high precision (0.1%) space-based photometric measurements of the Cepheid variable Polaris, obtained by the broad band Solar Mass Ejection Im…
Oscillations in Beta UMi - Observations with SMEI
N. J. Tarrant, W. J. Chaplin, Y. Elsworth +2
Aims: From observations of the K4III star Beta UMi we attempt to determine whether oscillations or any other form of variability is present. Methods: A high-quality photometric tim…
