Filter photometry
WebIn UBVRI photometry portions of a star’s spectrum are selected using optical filters. For such broad-band photometry the resulting passbands have a full-width half maximum (FWHM) ~ 100 nm (Majewski 2008). The sampling of a star’s spectrum by the passband is, however, a combination of the transmission of the WebACS Abell 370 is a massive galaxy cluster in the middle of a field of almost 8,000 galaxies. The Advanced Camera for Surveys (ACS) is a third-generation Hubble Space Telescope (HST) instrument installed in March 2002 during HST Servicing Mission 3B. The ACS CCD Electronics Box and Low Voltage Power Supply incrementally failed in June 2006 and …

WebThe transit method can be used to discover exoplanets. As a planet eclipses/transits its host star it will block a portion of the light from the star. If the planet transits in-between the star and the observer the change in light can be measured to construct a light curve. Light curves are measured with a charged-coupled device.
