Bibiana PrinothThey observed WASP-12 b 45 times with <a href="https://astrodon.social/tags/CHEOPS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CHEOPS</a> and used <a href="https://astrodon.social/tags/TESS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TESS</a> and <a href="https://astrodon.social/tags/Spitzer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Spitzer</a> data to study the phase curve including tidal deformation. Why is tidal deformation important? If you don’t account for the shape, you’ll overestimate the density of your planet. The phase curves allow to calculate the Love number which should tell us about the core mass fraction. Sadly not very well constrained, so we need <a href="https://astrodon.social/tags/JWST" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#JWST</a> for that instead. They’ll be doing that for WASP-103 b. <a href="https://astrodon.social/tags/ExSSV" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ExSSV</a>

Kelly LepoWhat a difference a large mirror makes!Here are two images of the same object, Herbig-Haro 46/47. HH 46/47 is a pair of jets launched by young stars.They are taken at similar wavelengths of infrared light. The difference? <a href="https://astrodon.social/tags/Spitzer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Spitzer</a>'s mirror was 85 cm (33 inches) in diameter, about the size of a hula-hoop. <a href="https://astrodon.social/tags/JWST" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#JWST</a>'s mirror is 6.6 meters (21.7 feet) in diameter, the height of a two-story building.Spitzer: <a href="https://www.spitzer.caltech.edu/image/ssc2003-06f1-embedded-outflow-in-hh-46-47" rel="nofollow noopener noreferrer" target="_blank">https://www.spitzer.caltech.edu/image/ssc2003-06f1-embedded-outflow-in-hh-46-47</a> JWST: <a href="https://webbtelescope.org/contents/media/images/2023/131/01H53089T1FMZZN48VD4Z73FRC" rel="nofollow noopener noreferrer" target="_blank">https://webbtelescope.org/contents/media/images/2023/131/01H53089T1FMZZN48VD4Z73FRC</a> <a href="https://astrodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://astrodon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a>
