Hāʻawi ʻo Neutron star 'glitch' i nā kānakaʻepekema i kahiʻike pehea e hana ai - BGR

ʻO ka hoʻāʻo ʻana i nā mea mamao ʻole i ka lewa hiki ke hoʻowalewale i ka poʻe astronomers, ʻoiai inā hoʻomaka kēia mau mea e hana i nā mea i manaʻo ʻole ʻia - a hiki ʻole i ka hoʻohālikelike ʻia. Manaʻo ʻia nā hōkū Neutron me nā mea waiwai loa i ka lewa a he ʻōlelo ʻepekema maikaʻi kēia o kā lākou hoʻokumu. Eia nō naʻe, ʻo kaʻano o kekahi mau hōkū neutron e "freeze" a i ʻole ka hana hewa ʻole ua waiho i nā poʻe astronomers i kāʻili wale i ko lākou mau poʻo. ka nānā ʻana i kahi hōkū neutron mamao kahi i kapa ʻia ʻo Vela Pulsar a wehewehe i kāna ʻano ponoʻī ʻoiai e kōkua ana i ka wehewehe ʻana i nā hana o loko o kēia mau mea hoihoi.

ʻO ke anuanu Neutron ka laulā maʻamau i ko lākou neʻe ʻana, e huli wikiwiki nei i ke kaʻe. he helu mau. Eia nō naʻe, ke lilo aku nei nā hōkū glitchy, hoʻomaka lākou e holo wikiwiki a maopopo ʻole ke kumu e tupu ai kēia hana.

ʻO ka Vela Pulsar kahi mea makemake nui ʻia no ka poʻe noiʻi no ka mea ke hālāwai pinepine nei ʻo ia i kēia mau pilikia i kēlā me kēia ʻelua a ʻekolu paha mau makahiki, a me ka nānā aku i kāna pilikia hope loa ma 2016 he mau clues i haʻalele ʻia ma mua. Ua ʻae ka ʻikepili i nā mea ʻepekema e nānā i loko o ka hōkū, e hōʻike ana i kona ʻano.

Wahi a ko lākou nānā ʻana, manaʻoʻiʻo nā mea noiʻi e hui pū ʻia nā hōkū i ʻekolu mau pūnaehana, me kahi pū i waho o ka pūpū e uhi ana i kahi "sop" o nā neutrons superfluid. Ke ho'ākāka nei ʻo ka haʻawina ʻana i ka wā e hoʻohiki ana kahi papa o kēia kime neutron e kū ana i loko o ka pūpuna, hoʻomaka ka hōkū e holo wikiwiki. Ua wehewehe nā ʻepekema ʻenehana i kēia hanana ʻo "kaʻe" ʻana. A laila e hoʻokau ka nalu lua o nā superfluid i ka mea mua, e hoʻihoʻi i nā mea i kahi kūlana kūpaʻa.

Ua pili kēia ʻike i kekahi mau ʻimi i mua i nā pilikia e pili ana i nā hōkū neutron. Hāpai aʻe i kahi nīnau hopohopo hou: ma mua o ka hiki ʻana o ka pilikia ma Vela, ke ʻano o ka lohi o ka hōkū ma mua o ka wikiwiki ʻana i ka wikiwiki, a hikiʻole ke ʻōlelo pehea e hana ai kēia "neʻe" i ka pilikia, akā hoʻopili ʻia nā mea ʻepekema.
