Gelioseysmologiya va Astroseysmologiya

1 Gelioseysmologiya va Astroseysmologiya 2 Artur S. Eddington: Yulduzlarning ichki tuzilishi, 1926 Artur Eddington (1882 - 1944) At first sight it would seem that the deep interior of the sun and stars is less accessible to scientific investigation than any other region of the universe. Our telescopes may probe farther and farther into the depths of space; but how can we ever obtain certain knowledge of that which is hidden behind substantial barriers? What appliance can pierce through the outer layers of a star and test the conditions within? 3 Gelioseysmologiya?? Quyosh tebranishlarini qayd etish orqali uning ichki tuzilishini o'rganish helios: Quyosh seismos: tebranish logos: tushuntirish, isbotlash Tovush - bu nima? 4 Chastotalar diapazoni 20 Hz to 20 00 Hz Летучая мышь~50 00 Hz Кит ~10 to 200 Hz Cолнце~ 3,3 mHz 5 Quyosh tebranishlarini o'rganish tarixi Samarqand 6 Aprel 17-19, 2014 6 IRIS dasturi 7 Quyosh tebranishlarining tabiati Tebranishlarning manbai konvektsiya hisoblanadi. Manbalar 300 km chuqurlikda joylashgan. Tebranishlar - konvektiv sohada joylashgan akustik to'lqinlar yoki р-modalar (pressure-mode) Nurlanish sohasida tarqaladigan tebranish modalari - g-modalar (gravity-mode). Qaytaruvchi kuchlar - gravitatsiya 8 Tebranishlar - bu turg'un akustik to'lqinlar 926 10 Tebranishlar - bu turg'un akustik to'lqinlar Past darajali modalar Yuqori darajali modalar 11 12 g-modalar p-modalar  = 1, m=0  = 1, m=1 T.
