... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...

This layer is defined with a <LAYER> tag. You see that the background color is applied to the rectangular region occupied by the layer. The height of the colored area is determined by the height value. This layer is defined in CSS syntax.

The style definition includes a value for layer-background-color. ...

Astronomers usually measure the flux of an object by collecting light with a telescope, sending it through a known filter, and then determining the power. ... But astronomers usually give their photometric results in terms of magnitudes. ... Astronomers define an absolute magnitude that is independent of the distance of a star and only depends on the intrinsic properties of the object: the absolute magnitude is the magnitude the star would have if it were 10 parsecs away from the Earth. ...
