Cepheid variable Study guides, Class notes & Summaries

 -1.5 magnitude Sirius appears 25x brighter than 2 magnitude Polaris.  “All neutron stars are pulsars, but not all pulsars are neutron stars” FALSE  “Spectroscopic Binary” is the term given to a pair of stars that we can determine are orbiting each other only by measuring their periodic Doppler shifts.  A 6.8 solar mass neutron star does NOT exist.  A loop of gas and charged particles following the magnetic field lines between sunspot’s poles is a Prominence/...

Vocabulary: absolute brightness, absorption spectrum, apparent brightness, Big Bang theory, blueshift, Cepheid variable, Doppler shift, Hubble constant, Hubble’s law, luminosity, megaparsec, period, redshift, spectrograph Gizmo Warm-up In 1912, an astronomer named Henrietta Swan Leavitt studied a class of stars called Cepheid variables. These stars change from bright to dim to bright again. Her discoveries led to a method of measuring distances to other galaxies and eventually helped to ...

GIZMOS Student Exploration; Big Bang Theory | Hubble’s Law 2023. Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Standing by the side of a lonely highway at night, you see two motorcycle headlights, one in each direction. The headlight on your left appears brighter than the one on your right. 1. If the headlights are equally bright, which motorcycle is closer? The one on the left side Explain: If it is brighter than that means its going to be closer because the light particle...

GIZMOS Student Exploration: Big Bang Theory – Hubble’s Law 2023. Collect data: Locate and select the yellow Cepheid variable star (A-091) in the lower left section of the Andromeda Galaxy. Click the Collect data button. You will see a graph of the apparent brightness of the star over time. A. How does the star’s apparent brightness change over time? It decreases, then increases, and decreases again. Its like a pattern. B. Turn on Show time probes. Set the left probe at the first brigh...
