Poyasnenie:
Issledovatel' vnutrennego stroeniya neitronnyh zvezd
(Neutron star Interior Composition Explorer –
NICER)
nahoditsya na bortu Mezhdunarodnoi kosmicheskoi stancii. On povorachivaetsya i naklonyaetsya,
chtoby sledit' za kosmicheskimi istochnikami rentgenovskogo izlucheniya, v to vremya kak stanciya
sovershaet oborot vokrug planety Zemlya kazhdye 93 minuty.
Rentgenovskie detektory vklyuchayutsya, kogda orbita stancii prohodit po
nochnoi storone.
Yarkie dugi i petli na etoi karte vsego neba pokazyvayut, kak NICER perevodilsya ot
odnoi celi k drugoi v techenie 22 mesyacev raboty.
Dugi shodyatsya k
yarkim pyatnam
– pul'saram na rentgenovskom nebe, kotorye NICER regulyarno nablyudaet.
Pul'sary – eto vrashayushiesya neitronnye zvezdy, izluchayushie regulyarnye impul'sy rentgenovskih luchei.
Promezhutki vremeni mezhdu impul'sami nastol'ko postoyanny, chto ih mozhno ispol'zovat' dlya
navigacii
– opredeleniya skorosti i polozheniya kosmicheskogo apparata.
Eta rentgenovskaya karta vsego neba ot NICER postroena tak, chto
nebesnyi ekvator
prohodit gorizontal'no cherez centr.
