Day 2 Binary Star Plots

The following plots are based on the data provided in the Time That Star! Day 2 Binary Data tables


Stellar Rotation Data

The following two data sets can tell astronomers how fast a star is rotating.

Cen X-3 Data

These data for Cen X-3 are rom EXOSAT satellite's Medium Energy experiment. All data are from 19 June 1985. The time is in seconds from the beginning of that day.
