An  analytical procedure was implemented in order to model the light  curves, color curves, and expansion-velocity curves. We find that  their V-I colors can be use as proxies of the extinction  caused by interstellar dust in their host galaxies. After the necessary corrections to photometry, we are able to recover the  correlation between luminosity and expansion velocity previously  reported in the literature for this supernova type. Given this and  assuming the standard extinction law, our Hubble diagrams show  dispersions of 0.4 magnitudes in the BVI filter bands. On the other  hand, if the extinction law is entered as a free parameter, we derive  final dispersions of 0.3 magnitudes, which implies that this kind of  supernova delivers distances as precise as 12%. The resulting extinction  law suggests a different interstellar medium in their host galaxies than  that of our Galaxy. Calibrating the correlation between luminosity  and expansion velocity, we obtain a Hubble constant of 70 km\/s\/Mpc, in  good agreement with modern measurements.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844302851\"\u003e\u003ch3\u003eThe Correlation between Luminosity and Expansion Velocity for Type II Plateau Supernovae\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844302851","offer_id":39497068052573,"sku":"9783844302851","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/8ef3d7da-8665-45c1-a7b3-91f3de672fb5.jpg?v=1773296797","url":"https:\/\/shop.autorenwelt.de\/products\/core-collapse-supernovae-as-standard-candles-von-felipe-olivares-e-und-mario-hamuy","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
