1) You want to observe a "monster" stellar flare on a young star referred to as a megaflare with 10,000 times more energy than the most powerful explosion ever observed on the Sun. Such a powerful eruption heats the plasma to the temperature of 220 million Kelvins, which is more than 10 times hotter than the temperature at the Sun's center. What type of technology (telescope, detector) will you use to observe such an event? Defend your choice.
At such high temperature (220 million kelvin) the matter involved in plasma state. Hence the energy released has shorter wavelength and higher frequencies greater than the visible region. Thats why it cannot be observed with help of telescopes. Energy from this event is in the form of X-Rays or Gamma rays. A detector such as scintillation detector using a cesium Iodide crystal will serve as an excellent X-ray detector.

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
choose A B C D QUESTION 1 Star formation in giant gas clouds is a result of competition between which forces? Light and rotation Light and dark Rotation and gas pressure Gravity and gas pressure 10 points QUESTION 2 What effect sets the largest size a star can have? The forming star is shining so strongly that it blows the collapsing gas cloud apart. If the star was any larger it would instantly form a Black Hole. If the...
Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...
