This bright star has high-energy attributes that are similar to the Sun, yet it is a hotter star, at the edge of the region in the H-R diagram where surface convection occurs (the power source for stellar magnetic activity). The HST part is to record STIS UV spectra of the bright ...
A breakthrough came in 1979 with the first detection of large-scale oscillations on the solar surface. These oscillations, or 'starquakes', are acoustic waves that penetrate the solar core - and hence provide information about the sound speed and, less directly, about the temperature and ...
However, increases in infrared surface temperature of the noses and differences in the visual thermal images of the noses were detected when animals began showing clinical signs of rabies. Differences were detected among the mean infrared nose temperatures for the disease progression intervals ($F_{3...

Shanghai has a northern subtropical monsoon climate, with annual average precipitation of 1122 mm and annual mean temperature of 15.8 °C (Wu et al., 2012). The area surrounding Shanghai is originally rich in biodiversity, e.g., a survey in 2004 reported 760 vertebrate species, consisted of...
differential rotation for a class of models of Procyon, consistent with the presently available astrometric and asteroseismic data, and the related rotational splittings. As the evolutionary mod- els of Procyon show that the mass in the surface convection ...
A comparison was made between predicted and observed fur surface temperatures, and heat losses from the top, side, and bottom. Under these conditions, transfer coefficients derived from engineering relationships can be dependably used in the field; the average difference between predicted and observed...
We use the LETGS spectra to carry out density and temperature diagnostics with an emphasis on the H- like and the He-like ions. We find a correlation between line flux ratios of the Ly(alpha) and He-like resonance lines with the mean X-ray surface flux. We determine densities using ...
The model was tested by simulating an overwintering raccoon with a fur covered, electrically heated cylinder in a closed den and comparing predicted and observed fur surface temperatures and heat losses from the model top, side, and bottom.Jeffrey Thorelson...
