We present an abundance analysis of light elements in the most massive chemically peculiar (CP) stars, He-rich stars. The analysis is based on both low and high-resolution observations collected at ESO, La Silla, Chile in the optical region and includes 6 standard and 21 He-rich stars. Light element abundances display a diverse pattern from under-solar up to above-solar values. ...

Each Apache configuration directive is described using a common format that looks like this: . ... This indicates the format of the directive as it would appear in a configuration file. This syntax is extremely directive-specific, and is described in detail in the directive's definition. ... If the directive has a default value ( i.e. , if you omit it from your configuration entirely, the Apache Web server will behave as though you set it to a particular value), it is described here. ...

SN 1989B Light Curve Analysis. ... In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif).

spaceweb@oulu.fi - last update: 12 February 1999, 1015 UT . Sun emits radio energy with a slowly varying intensity. This radio flux, originating from atmospheric layers high in the Sun's chromosphere and low in its corona, changes daily with the sunspot number, and thus also follows the solar cycle . This is seen from the figure displaying the flux at 2800 MHz or 10.7 cm wavelength over the entire solar disk (in here, monthly averages, although daily values exist too). ...
