Maia Nebula \/\u00a0<\/em>NGC\u00a01432<\/em><\/b> is a\u00a0star<\/a>\u00a0in the\u00a0constellation<\/a>\u00a0of\u00a0Taurus<\/a>. It is the\u00a0fourth-brightest star<\/a>\u00a0in the\u00a0Pleiades<\/a>\u00a0open star cluster<\/a>\u00a0(M45<\/a>), after\u00a0Alcyone<\/a>,\u00a0Atlas<\/a>\u00a0and\u00a0Electra<\/a>, in that order. Maia is a\u00a0blue giant<\/a>of\u00a0spectral type<\/a>\u00a0B8 III, and a\u00a0mercury-manganese star<\/a>.<\/p>\n Maia’s\u00a0visual magnitude<\/a>\u00a0is 3.871, requiring darker skies to be seen. Its total\u00a0bolometric<\/a>\u00a0luminosity<\/a>\u00a0is 660 times solar, mostly in the\u00a0ultraviolet<\/a>, thus suggesting a radius that is 5.5 times that of the Sun and a mass that is slightly more than 4 times solar.<\/sup>\u00a0It was thought to be a\u00a0variable star<\/a>\u00a0by astronomer\u00a0Otto Struve<\/a>. A class of stars known as\u00a0Maia variables<\/b>\u00a0was proposed, which included\u00a0Gamma Ursae Minoris<\/a>, but Maia and some others in the class have since been found to be stable.<\/sup><\/p>\n Maia is one of the stars in the\u00a0Maia Nebula<\/b>\u00a0(also known as\u00a0NGC 1432<\/i>), a bright emission or reflection nebula<\/sup>\u00a0within the Pleiades star cluster.<\/p>\n Source: Wikiepedia<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Recording description Recorded with my Boren-Simon 10″ telescope and Apogee Ultra 8300 CCD with narrow band filters: Luminance #1: 20 minutes (Boren Simon, 10″ and\u00a0Apogee Ultra 8300 CCD) Luminance #2: 30 minutes (T18, iTelescope.net) RGB: 10,10,10 minutes Processed with: MaximDL (stacking + DDP), PI (aligning and color combine), PS (features) Object description […]<\/p>\n","protected":false},"author":1,"featured_media":2144,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true},"categories":[1],"tags":[],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/starworks.dk\/wp-content\/uploads\/2017\/11\/Maia-Nebula-LRGB_PI_PS_LessNoise.jpg?fit=2394%2C1880","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/s6fUB9-ngc1432","jetpack_likes_enabled":true,"jetpack-related-posts":[{"id":2120,"url":"http:\/\/starworks.dk\/ngc4214\/","url_meta":{"origin":2143,"position":0},"title":"NGC4214","date":"01\/05\/2016","format":false,"excerpt":"Recording description Recorded with my Boren-Simon 10\" telescope and Apogee Ultra 8300 CCD with narrow band filters: Luminance: 65 minutes Ha: 75 minutes O3: 80 minuntes Processed in PixInsight and Photosop CS6.
