GRS 1915+105 sahifasining manbasini koʻrish

'''GRS 1915+105''', '''V1487 Orla''' ― rentgen qoʻshaloq yulduzi boʻlib, uning komponentlaridan biri oddiy yulduz, ikkinchisi esa [[qora tuynuk]]. Tizim 1992-yil 15-avgustda „Granat“ (GRANAT) kosmik observatoriyasining WATCH asbobida kuzatuvlar paytida topilgan. „GRS“ „GRANAT tomonidan kuzatilgan manba“ degan maʼnoni, „1915“ — toʻgʻri koʻtarilish (19 soat 15 daqiqa), „105“ — taxminiy moyillikni (10 daraja 56 daqiqa) anglatadi.
