List of Keywords

Key words will be included for all published papers. Authors should select key words using the list given below.

Usually no more than five key words will be needed. In listing choices, the overall categories (which are indented) should not be included. Do not include any part of a keyword that is in parentheses below: thus, '(stars:) binaries (including multiple): close' should be given as 'binaries: close'.

The key words should appear following the abstract, in alphabetical order, each separated by an "em" dash, or by -- as in the following example:

Key words: galaxies: evolution -- galaxies: individual (NGC 6822) -- galaxies: irregular -- stars: evolution

Key words such as 'galaxies: individual (..., ...)' should include the individual names in parentheses, as indicated above.
