In autumn 1994, two groups of astronomers announced that they had discovered Cepheid variable stars in a distant cluster of galaxies. ... As the term suggests, variable stars change in brightness over time. ... Variable stars are an ideal way to get high-school students doing real science, with real data, from the real sky. ... a sky chart to find the stars . ... Students can use the nearby stars to estimate the magnitude of Delta. ... Locate the star Delta in Cepheus and estimate its brightness . ...

... Some data selection widgets for plotting display more indices than needed for some of the plot variables in order to avoid recycling of the data selection widget if the variables change. ... They are organized by class, even though, strictly speaking, an plot class refers only to a specific selection of variables listed in a plot selection widget. ... Also note that the IDL variables in italic font denote a derivation from this variable, i.e. the data is not exactly identical to the variable...

... Stars . ... Cepheid variable stars have been known since the 18th century. ... Regularly brightening to a peak over days, weeks or months before fading these variable stars were remarkable curiosities to astronomers in past centuries.€а The term Cepheid is taken from the star Delta Cephei in the constellation of Cepheus, which was identified as variable€а in 1784 by the teenaged prodigy John Goodricke (1764-96). ... Tweets that mention Cepheids: Inconstant Stars which break the rules | ...

... Time delay determinations in astrophysics are used most often to find time delays between flux density variations in different spectral bands and/or lines in AGNs, and different images of gravitationally lensed QSOs. ... OB used an idea to take into account the known gravitational lensing time delay to get combined radio and optical light curves and then to use them for determination of the possible radio-from-optical time delay. ... Correction for change of time delay and radio flux. ...

The C and TC shells have a number of local shell variables which are not exported to the environment. To make sure that these variables are picked up whenever a new shell is invoked, always define shell variables in your .cshrc ( .tcshrc ) file. By convention, names of shell variables are always given in lower case letters. UNIX is case sensitive, so the environment variable PATH is not the same as the shell variable "path". ... Setting shell variables . ...

Normally, this is already set to the ETC directory of the TCP/IP code, such as SET ETC=C:\TCPIP\ETC For Warp 4 and later, this may point to the \MPTN\ directory. ... Normally you will set this variable to the same value as the HOSTNAME variable and simply add a :0.0 after it, such as SET DISPLAY=myhost:0.0 Read the X11 man page on the exact meaning of these postfixes and other options. ...

... Help the observer to classify the variables as classical Cepheids (C1), type II Cepheids (C2) and RR Lyrae stars (R). ... Notes: Classical Cepheid stars are a type of pulsating variable stars, which show linear relationship between period of pulsation and absolute luminosity in a log-log plot. ... RR Lyrae stars are another type of pulsating variable stars which show very short period (less than 1 day) of pulsation and for all RR Lyrae stars, the absolute luminosity is nearly constant. ...
