<h2 id="nomenclature">Nomenclature</h2> <p>In August 2022, this planet and its host star were included among 20 systems to be named by the third <a href="/facts/NameExoWorlds/NpRMt4m0">NameExoWorlds</a> project.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> The approved names, proposed by a team from Brandon Park Primary School in <a href="/facts/Wheelers_Hill/1rMXdJXa">Wheelers Hill</a> (<a href="/facts/Melbourne/EHY9YxI0">Melbourne</a>, <a href="/facts/Australia/qLHpbppq">Australia</a>), led by scientist Lance Kelly and teacher David Maierhofer <a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> were announced in June 2023. WASP-19b is named Banksia and its host star is named Wattle, after the <i><a href="/facts/Banksia/2cdsI3g6">Banksia</a></i> and <a href="/facts/Acacia_sensu_lato/6voSELsk">wattle</a> plants.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p> <h2 id="atmosphere">Atmosphere</h2> <p>In December 2013, scientists working with the <a href="/facts/Hubble_Space_Telescope/NQeIf0vw">Hubble Space Telescope</a> reported detecting <a href="/facts/Water/0lkXnJPK">water</a> in the <a href="/facts/Atmosphere/oUpLaGRF">atmosphere</a> of the <a href="/facts/Exoplanet/zjfmqfUf">exoplanet</a>.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a><a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p><p>In September 2017, astronomers using the <a href="/facts/Very_Large_Telescope/xUQCLysQ">Very Large Telescope</a> at the <a href="/facts/European_Southern_Observatory/mJtjDbwx">European Southern Observatory</a> reported the detection of <a href="/facts/Titanium(II)_oxide/5ek4Vasd">titanium oxide</a> (TiO) in WASP-19b's atmosphere.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> This was the first time titanium oxide had been detected in an exoplanet atmosphere.<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> They also detected a strongly scattering <a href="/facts/Haze/83dMNDgj">haze</a> in the atmosphere as well as the element <a href="/facts/Sodium/eYuSPu2V">sodium</a>, and additionally confirmed the presence of water.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> Strong haze and barely discernible titanium oxide signal were confirmed in 2021, while no sign of water or alkali metals can be found.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> </p><p>A study using <a href="/facts/Transiting_Exoplanet_Survey_Satellite/IxEjYsYd">TESS</a> data concluded that the atmosphere of WASP-19b is moderately efficient at transporting heat from the dayside to the nightside.<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> </p> <h2 id="external-links">External links</h2> <p> Media related to WASP-19b at Wikimedia Commons </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"2022 Approved Names". nameexoworlds.iau.org.
