Korotatsiya doirasi

Korotatsiya doirasi – spiral galaktikaning galaktik markazi atrofidagi aylana boʻlib, unda yulduzlar spiral qoʻllar bilan bir xil tezlikda harakatlanadi. Bu doiraning radiusi korotatsiya radiusi deb ataladi. Doira ichida yulduzlar spiral qoʻllardan tezroq, uning tashqarisida esa sekinroq harakat qiladi.

Quyosh Somon yoʻlining korotatsion doirasi yaqinida joylashgan^[1]^[2].
