Ca Ii H And K And Hydrogen-Line Variations In V471 Tauri (=Bd + 16°516), Terry D. Oswalt
Ca Ii H And K And Hydrogen-Line Variations In V471 Tauri (=Bd + 16°516), Terry D. Oswalt
Publications
Spectroscopic and narrow-band photoelectric observations of the white dwarf eclipsing binary V471 Tau (= BD + 16°516) are reported. Periodic fluctuations in Ca IIH and K emission and Ha absorption, and a wave-like distortion of the light curve mimic the characteristics of several well-observed RS CVn binaries. A probable correlation between maximum emission-line strength and wave minimum is shown to exist.

A Computerized Demonstration Of The Central Limit Theorem In Statistics, Paul S. T. Lee
Publications
The Central Limit Theorem is one of the most important concepts in statistics. It provides a link between sample statistics and population parameters. It is a basic concept for understanding various hypothesis-testing techniques such as Student's t-distribution, x2-distribution and F-distribution.
