Kua korerohia e nga Kaitirotiro whetu kua kitea tetahi mea kiato tata ki te 2.35 papatipu ra i roto i te kahui aorangi NGC 1851 i roto i to maatau kainga. tupuni Milky Way. Na te mea kei te pito o raro tenei o "pango pango mass-gap”, he neutron nui pea tenei mea kiato whetu te mea mama ranei pango pango he momo whetū tē mōhiotia rānei. Ko te ahua tika o tenei tinana kaore ano kia whakatauhia. Heoi, ko te mea pai ake ko tera, kaore i rite ki te tinana kiato rite i kitea i roto i te huihuinga hanumi GW190814, ka kitea tenei tinana kiato i roto i te hanganga punaha rua hei hoa mo te pulsar. Mena ka whakatauhia tenei tinana kiato i roto i te hanganga rua me te pulsar he a pango pango a meake nei, koinei te tuatahi "pulsar - pango pango punaha" e mohiotia ana.
Ka pau te wahie, ka hanumi karihi i roto i te whetu ka mutu, karekau he kaha ki te whakamahana i nga rawa hei taurite i te kaha o roto o te taumahatanga. No reira, ka hinga te uho ki raro i tona kaha, ka mahue mai he kiato nohonga. Ko te mutunga tenei o te whetu. Ko te whetu mate ka huri hei papaka ma, hei whetu neutron ranei pango pango kei runga i te papatipu o te whetu taketake. Ko nga whetu kei waenga i te 8 ki te 20 nga papatipu solar ka mutu hei whetu neutron (NSs) ka piki ake nga whetu taumaha. pango pango (BHs).
Te papatipu mōrahi o whetu neutron he 2.2 nga papatipu solar i te wa pango pango ka hanga i te mutunga o te huringa ora whetu he nui ake i te 5 papatipu solar. Tenei papatipu-aputa i waenganui i te kohao pango tino marama (ara 5 M⊙) me te neutron tino taumaha whetu (ara 2.2 M⊙) e kiia ana ko “black hole mass-gap”.
Ahanoa kiato i roto i te "pango pango āputa papatipu”
Ko nga mea kiato ka taka ki roto i te papatipu-aputa (i waenga i te 2.2 ki te 5 papatipu ra) kare e kitea i te nuinga o te waa, kaore hoki e tino marama. Ko etahi mea kiato i kitea i roto ngaru taipapa Ko nga huihuinga kei roto i tenei rohe papatipu-aputa. Ko tetahi o enei tauira ko te kitenga o te papatipu kiato o te 2.6 papatipu solar i te 14 o Akuhata 2019 i roto i te huihuinga hanumi GW190814 i puta he poka pango whakamutunga tata ki te 25 papatipu solar.
Ahanoa kiato i roto i te papatipu-aputa i roto i te hanganga "pūnaha rua".
No tata nei i kii mai nga kaiputaiao i te kitenga o taua mea kiato mo te 2.35 papatipu solar i roto i te kahui aorangi NGC 1851 i roto i to tatou tupuni kainga Milky Way. Na te mea kei te pito o raro tenei o "pango pango mass-gap”, he neutron nui pea tenei mea kiato whetu te mea mama ranei pango pango he momo whetū tē mōhiotia rānei.
Ko te ahua tika o tenei tinana kaore ano kia whakatauhia.
Heoi, ko te mea pai ake ko te mea, kaore i rite ki te tinana kiato rite i kitea i roto i te huihuinga hanumi GW190814, ka kitea tenei tinana kiato i roto i te hanganga o te punaha rua hei hoa mo te pulsar rua millisecond.
Mena ka whakatauhia tenei tinana kiato i roto i te hanganga rua me te pulsar he a pango pango a meake nei, koinei te tuatahi "pulsar - pango pango punaha" e mohiotia ana. Koinei te mea e rapuhia ana e nga kaitoro arorangi pulsar mo nga tekau tau.

Because this is at the lower end of “black hole mass-gap", this compact object could be either a massive neutron star or the lightest black hole or some unknown star variant. The exact nature of this body is yet to be determined. However, what is more interesting is that, unlike the similar compact body detected in the merger event GW 190814, this compact body is found in binary system formation as the companion of a pulsar. If this compact body in binary formation with the pulsar is determined to be a black hole in future, this would be the first “pulsar - black hole system” known. ){kind=link}
