However, the discovery of many close-in orbiting sub-Neptunes, if at least some of them are water worlds, challenges this notion. Therefore, many sub-Neptunes have been thought to be large Earth-like planets with thick, hydrogen-rich atmospheres. We conducted a series of<br>experiments under the pressure-temperature conditions expected at the boundary between a hydrogen-rich atmosphere and the rocky interior of a sub-Neptune. We discovered reaction between hydrogen and magma that can release oxygen from silicate magma, allowing it to react with hydrogen and form water. This chemical reaction can transform a dry, hydrogen-rich planet into a water-rich planet even inside the snow line. I will also discuss how such reactions can impact the atmosphere, the interior, the size demographics, and the potential habitability of super-Earth exoplanets, many of which may have originated as sub-Neptunes.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zoom Link for Colloquium 10\/31\/2023 3:00pm PST Please email astrobio@uw.edu for zoom presentation password Presented by Dan Shim Professor, School&hellip;<\/p>\n","protected":false},"author":1,"featured_media":5907,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0},"categories":[40,13,12],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5906"}],"collection":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/comments?post=5906"}],"version-history":[{"count":1,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5906\/revisions"}],"predecessor-version":[{"id":5908,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5906\/revisions\/5908"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/media\/5907"}],"wp:attachment":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/media?parent=5906"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/categories?post=5906"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/tags?post=5906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
