Ke hōʻike nei ka European Southern Observatory (ESO) i ka ESO's Very Large Telescope-Interferometer (VLTI) GRAVITY instrument i hana mua i ka nānā pono ʻana o kahi exoplanet me ka hoʻohana ʻana i ka interferometry optical.
Ke kamaʻilio nei mākou e pili ana i ka honua HR8799e, ka mea e hoʻopuni ana i ka hōkū ʻōpio HR8799, aia ma kahi mamao ma kahi o 129 mau makahiki māmā mai ka Honua ma ka hōkū ʻo Pegasus.
ʻIke ʻia i ka makahiki 2010, ʻo HR8799e he super-Jupiter: ʻoi aku ka nui o kēia exoplanet a ʻoi aku ka ʻōpio ma mua o kekahi honua ma ka Pūnaehana Solar. Ua manaʻo ʻia ka makahiki o ke kino ma 30 miliona mau makahiki.
Ua hōʻike ʻia ka nānā ʻana he honua ʻino loa ʻo HR8799e. ʻO ka ikehu pau ʻole o ka hoʻokumu ʻana a me ka hopena ʻōmaʻomaʻo ikaika i hoʻomehana i ka exoplanet i kahi mahana ma kahi o 1000 degere Celsius.
Eia kekahi, ua ʻike ʻia he lewa paʻakikī ka mea me nā ao hao-silicate. I ka manawa like, ua uhi ʻia ka honua holoʻokoʻa i kahi ʻino nui.
"Ke hōʻike nei kā mākou ʻike i ke ola ʻana o kahi pōleʻa kinoea i hoʻomālamalama ʻia mai loko mai, me nā kukuna o ka mālamalama e haki ana i nā wahi ʻino o nā ao ʻeleʻele. Hana ʻia ka convection ma nā ao i loko o nā ʻāpana hao-silicate, ua luku ʻia kēia mau ao a hāʻule ko lākou mau mea i ka honua. Hoʻokumu kēia mau mea āpau i ke kiʻi o ka lewa ikaika o kahi exoplanet nunui i ke kaʻina o ka hānau ʻana, kahi e hana ai nā kaʻina hana kino a me ke kemika, "wahi a nā loea.
