Zvishandiso zvitsva uye zvitsva zvinoonekwa zvezvinhu zvakafukunurwa kwenguva refu zvinotibvumira kuona mufananidzo wakajeka weChisiko chakatipoteredza. Saka, makore matatu apfuura, iyo shell spectrograph yakatanga kushanda nekururama kunoshamisa kusvika zvino huwandu hweiyo exoplanet yepedyo kwatiri muProxima Centauri system. Kurongeka kwechiyero kwaive 1/10 yehuremu hwePasi, iyo nguva pfupi yadarika yaigona kunge yakatorwa sengano yesainzi.
Kuvapo kweiyo exoplanet Proxima b yakatanga kuziviswa muna 2013. Muna 2016, European Southern Observatory's (ESO) HARPS spectrograph yakabatsira kuona huwandu hunofungidzirwa hweiyo exoplanet, yaive 1,3 yePasi. Ongororo ichangobva kuitika yenyeredzi dzvuku inonzi Proxima Centauri achishandisa ESPRESSO shell spectrograph yakaratidza kuti huremu hweProxima b huri pedyo nehwePasi uye hunorema 1,17 hwepasi redu.
Nyeredzi dzvuku diki Proxima Centauri inowanikwa makore 4,2 chiedza kubva kuhurongwa hwedu. Ichi chinhu chakanyanya nyore kudzidza, uye zvakanaka kwazvo kuti exoplanet Proxima b, iyo inotenderera iyi nyeredzi nenguva yemazuva 11,2, yakave ingangoita mapatya ePasi maererano nehukuru uye saizi maitiro. Izvi zvinovhura mukana wekuwedzera kudzidza kwakadzama kweiyo exoplanet, iyo ichaenderera mberi nerubatsiro rwezviridzwa zvitsva.
Kunyanya, European Southern Observatory muChile ichagamuchira itsva High Resolution Echelle Spectrometer (HIRES) uye RISTRETTO spectrometer. Zviridzwa zvitsva zvichaita kuti zvikwanise kurekodha spectra inoburitswa neiyo exoplanet pachayo. Izvi zvichaita kuti zvikwanise kudzidza pamusoro pekuvapo uye, zvichida, kuumbwa kwemhepo yaro. Nyika iri munzvimbo inodaidzwa kugarika yenyeredzi yayo, izvo zvinotitendera kuti tive netariro yekuvapo kwemvura yemvura pamusoro payo uye, pamwe, nekuvepo kwehupenyu hwehupenyu.
Panguva imwecheteyo, zvinofanirwa kuyeukwa kuti Proxima b iri padyo nenyenyedzi yayo kakapetwa makumi maviri pane iyo Nyika iri kuZuva. Izvi zvinoreva kuti exoplanet inoratidzwa kune 20 nguva yakawanda nemwaranzi kupfuura Earth. Mhepo yakakora chete ndiyo inogona kuchengetedza hupenyu hwehupenyu pamusoro peiyo exoplanet. Masayendisiti anotarisira kuwana ese aya nuances mune ramangwana zvidzidzo.
