studying high energy physics, stellar evolution and mass-loss processes, compact objects, cosmology, nucleosynthesis, and galaxy evolution. Optical transient surveys such as ZTF, ATLAS, ASAS-SN now find thousands of supernovae and other explosive transients per year, and these numbers will increase exponentially once the Vera Rubin Observatory LSST survey starts in 2024-2025. We use primarily optical follow-up and pre-explosion observations (imaging and long-slit\/IFU spectroscopy) of supernovae and their host galaxies obtained with a variety of telescopes (small to large aperture) to constrain their progenitor stars, explosion and powering mechanisms. We are interested in studying core-collapse and thermonuclear supernovae, including normal events and rarer sub-classes and weirdos. We are also interested in other types of explosive transients such as tidal disruption events (and their host galaxies) and intermediate luminosity transients.<\/p>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-3a0162a\" data-id=\"3a0162a\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-15bfe60 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"15bfe60\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-867a2f5\" data-id=\"867a2f5\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ade64c5 elementor-view-stacked elementor-widget-mobile__width-initial elementor-shape-circle elementor-widget elementor-widget-icon\" data-id=\"ade64c5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"icon.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-icon-wrapper\">\n\t\t\t<div class=\"elementor-icon\">\n\t\t\t<i aria-hidden=\"true\" class=\"hm hm-team-member\"><\/i>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-0ff802d\" data-id=\"0ff802d\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ac88341 elementor-widget elementor-widget-heading\" data-id=\"ac88341\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h6 class=\"elementor-heading-title elementor-size-default\">People<\/h6>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-1d7b637 elementor-widget__width-initial dark-background-links elementor-widget elementor-widget-text-editor\" data-id=\"1d7b637\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li style=\"text-align: left;\"><a href=\"https:\/\/astronomia.udp.cl\/en\/researcher\/jose-prieto\/\" target=\"_blank\" rel=\"noopener\">Dr. Jose Prieto<\/a><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-b482258 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"b482258\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-59a6667\" data-id=\"59a6667\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-27d9859 elementor-widget elementor-widget-spacer\" data-id=\"27d9859\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Supernovae, Transients, and Variable Stars Research Projects Progenitors stars, Explosion and Powering mechanisms of Supernovae and other Explosive Transients Progenitors stars, Explosion and Powering mechanisms of Supernovae and other Explosive Transients &times;
