1. Astronomy HyperText Book: Stellar Evolution
... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

2. Development of an ADS Data Dictionary Standard
... We present a proposed standard for data dictionaries associated with catalogs being accessed through the Astrophysics Data System (ADS) Mosaic Catalog Service. Each catalog made available for searching must have a data dictionary, which consists of a set of specified keywords describing format, content and location of data. ... There are two keywords in the Table Data Dictionary which indicate to the server software that the corresponding column contains special attributes. ...

3. Standard values
... Standard-star files, however, must also have the standard photometric values (in place of the rough MAG column). The column label should be the usual name of the magnitude or index in the column, e.g., V or U-B or c1; see Table . ... MIDAS table files do not distinguish between upper and lower case in column labels. Thus, while it is possible to use 'u-b' as a column label for the uvby system, it cannot be distinguished from 'U-B' by programs or MIDAS procedures that read these files. ...

5. Standard Patterns for Substepping and Background Measurement
... This table shows how each STEP-PATT pattern measures the background for a science exposure. Listed are the STEP-PATT number, the number of spectrum bins for which substepping occurs, the number of background bins measured, the diodes used to measure the background, the fraction of the total time spent measuring flux on the science diodes, the gratings for which the STEP-PATT is appropriate, and the shortest exposure that can be used for that pattern. ... Table 8.3: - STEP-PATT Specifications . ...
