European Southern Observatory (ESO) ikunena kuti chida cha ESO's Very Large Telescope-Interferometer (VLTI) GRAVITY chidawona koyamba mwachindunji za exoplanet pogwiritsa ntchito optical interferometry.
Tikulankhula za dziko la HR8799e, lomwe limazungulira nyenyezi yaing'ono HR8799, yomwe ili pamtunda wa zaka pafupifupi 129 kuchokera ku Dziko Lapansi mu gulu la nyenyezi la Pegasus.
Zinapezeka mu 2010, HR8799e ndi Jupiter wapamwamba kwambiri: exoplanet iyi ndi yayikulu kwambiri komanso yaying'ono kwambiri kuposa pulaneti lililonse mu Solar System. Zaka za thupi zimayesedwa zaka 30 miliyoni.
Zowonera zawonetsa kuti HR8799e ndi dziko laudani kwambiri. The unspent mphamvu ya mapangidwe ndi wamphamvu wowonjezera kutentha kwenikweni mkangano ndi exoplanet kutentha pafupifupi 1000 digiri Celsius.
Komanso, zidapezeka kuti chinthucho chili ndi mlengalenga wovuta komanso mitambo yachitsulo-silicate. PanthaΕ΅i imodzimodziyo, dziko lonse lapansi lili ndi chimphepo champhamvu kwambiri.
"Zomwe taziwona zikuwonetsa kukhalapo kwa mpira wa gasi wowunikiridwa kuchokera mkati, ndi kuwala komwe kumadutsa m'malo odzaza ndi mkuntho wa mitambo yakuda. Convection imachita pa mitambo yokhala ndi tinthu tachitsulo-silicate, mitambo iyi imawonongeka ndipo zomwe zili mkati mwake zimagwera padziko lapansi. Zonsezi zimapanga chithunzi cha mlengalenga wamphamvu wa exoplanet yaikulu mu nthawi ya kubadwa, momwe njira zovuta za thupi ndi mankhwala zimachitika, "akutero akatswiri.
