Спутник ФКИ. AstroSat. [Редактировать]

AstroSat это первый астрономический спутник Индии. Его запуск состоялся в конце сентября 2015 года при помощи ракеты-носителя PSLV. По своему целевому предназначению космический аппарат является многоволновой миссией по изучению космоса. Спутник будет запущен на экваториальную орбиту Земли. Обсерватория будет иметь 5 различных приборов изучающих видимое (320—530 нм), ультрафиолетовое (130—320 нм), рентгеновское (0,3—8 кэВ, 2—10 кэВ, 3—80 кэВ и 10—150 кэВ) излучения.
Научные задачи:

  • Многоволновое исследование космических объектов.
  • Обзор неба в жёстком рентгене и ультрафиолетовом диапазоне спектра.
  • Широкополосные спектрографические исследования активных галактических ядер, остатков сверхновых и звёздных корон.
  • Исследования периодической и непериодической изменчивости источников рентгеновского излучения.
  • Контроль интенсивности известных источников излучения сигналов, обнаружение вспышек и изменений яркости космического пространства.

Полезная нагрузка:

  • Ультрафиолетовый телескоп (UVIT) - ультрафиолетовый телескоп должен выполнить трех канальную съемку в диапазонах: 130-180 нм, 180-300 нм и 320-530 нм. Поле обзора круговое ~ 28 аркмин в диаметре с 1.8" угловым разрешением для ультрафиолетового канала и 2.5" для видимого канала. Каждый из трех каналов может быть выбран при помощи фильтров установленных на инструментов. В дополнение к трем режимам инструмент способен снимать в двух каналах одновременно с разрешением около 100.
  • Soft X-ray телескоп (SXT) - Soft X-ray телескоп на аппарате Astrosat должен фокусировать оптические и глубоко истощенные CCD камеры на фокальную плоскость для съемки X-ray изображений в диапазоне 0.3-8.0 кЭв. Оптика состоит из 41 концентрических поверхностей покрытых золотом в конфигурации Wolter-I. Фокальные планки CCD камеры заимствованы с прибора SWIFT XRT. CCD работают при температуре около −80 °C, а следовательно на инструмент была установлена система охлаждения.
  • LAXPC - инструмент для съемке X-лучей и работы в низком низкого разрешении (в диапазоне 3-80 кЭв) Astrosat должен будет использовать кластер из 3 совмещенных идентичных Large Area X-ray Proportional Counters (LAXPCs), каждый в мультипроводной, многоуровневой архитектуре с полем наблюдения of 1° × 1°.
  • Cadmium Zinc Telluride Imager (CZTI) - Astrosat имеет на своем борту сенсор жесткого ренгеновского излучения. Он состоит из крупнозернового Кадмий-цинкиевого телларуда и имеет площадь около 1 квадратного метра. Этот детектор обладает хорошей чувствительностью и обеспечивает работу в диапазоне до 100 кЭВ с разрешающей способностью ~ 2 процента на уровне 60 кЭв. Малый размер зерен также позволяет получить среднее разрешение при съемке жесткого рентгеновского излечения.
  • Scanning Sky Monitor (SSM) - Scanning Sky Monitor будет состоять из трех сенсоров которые конструктивно будут состоять из трех трубок которые заполнены газом в котором будут находиться в качестве сопротивления провода. При прохождении рентгеновского излучения детекторы будут излучать свет, что должно будет фиксироваться оптическими сенсорами.
  • Charged Particle Monitor (CPM) - детектор заряженных частиц (CPM) должен будет измерять параметры потока низкоэнергетических протонов и электронов

12016-08-31. Космический аппарат AstroSat впервые наблюдал ренгеновское излучение от черных дыр.
Индийская обсерватория AstroSat, которая была запущена ISRO в сентябре 2015 года, произвела свое первое наблюдение высокоэнергетических частиц и ренгеновского излучения, которые испускались черной дырой. Согласно существующим представлениям данный процесс сопровождает процесс падения вещества на объекты большой массой. При этом, температура диска вокруг черной дыры приближается к 10 млн. градусов Цельсия.Тэги: AstroSatКосмическое агентство Индии
