... 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. ...

... The frames, as they appear on the monitor with the command LOAD/IMAGE , are in general not oriented properly. ... This means that the frames have to be rotated in such a way that: . ... ROTATE/ECHELLE inputspec outframe mode . ... The command ROTATE/ECHELLE sets descriptor values START and STEP to 1.,1. for all images and updates the session keyword CCDBIN to the original steps of the images. These operations must be performed by the user if another command than ROTATE/ECHELLE is applied. ...

... The material in "From Stargazers to Starships" meets several important requirements of the national standards. Pages cited below are from National Science Education Standards National Academy Press, Washington 1995. ... For example: the sections on astronomy not only describe calendars and sundials (including their construction), but also the astronomy of the ancient Greeks, including two different ways in which ancient Greeks estimated the distance to the Moon. ...

... Standard Commands . ... TwistedActor.Actor is core code for writing an actor: an instrument control computer (ICC) or hub-based script that does something useful. This manual describes the standard commands and keywords that any actor based on TwistedActor.Actor will support. All actors based on TwistedActor typically support the following standard commands (plus additional device-specific commands documented in that actor's manual). ... Connect one or more devices (if not already connected). ...

... Standard magnitudes can only be computed for the U, B and V filters and hence the only standard colours that can be calculated are U-B, B-V and U-V. An important point to note, is that these standard colours can be computed using the following instrumental colours - U-B, B-V, U-V, (UVW1-U), (UVW1-B), (UVW1-V), (UVW2-B) and (UVW2-V). Omsrclistcomb computes all possible standard magnitudes for each of the U, B and V filters and displays them in a vector column. ...
