  4. REACH FOR THE STARS, Division B DESCRIPTION: Students will demonstrate an understanding of the properties and evolution of stars and their observation with different portions of the electromagnetic Spectrum: Radio, Infrared, Visible, Ultraviolet, X-Ray and Gamma Ray. EVENT PARAMETERS: Each team may bring only two 8.5”x11” two-sided pages of notes containing information in any form from any source and must provide their own clipboards and red-filtered flashlights. Part I: Constellation, Star, and Deep Sky Object (DSO) Identification Part II: i: Stellar Evolution stellar nurseries, protostars, main sequence stars, red giants, planetary nebulas, white dwarfs, red supergiants, Type Ia supernovas, Type II supernovas, neutron stars/pulsars, and black holes ii: Spectral Classification of Stars spectra and the H-R diagram iii: The Electromagnetic Spectrum multiwavelength observations iv: Stellar Temperatures, Radii, and Luminosities the H-R diagram, blackbody radiation
