The most massive stars in the Universe have a surface temperature that can reach over 50 000 K. Life on planets like Earth cannot exist at 1AU from such stars, it's too hot. Find the emitted power per square meter of peak intensity for a similar star with 43000 K that emits thermal radiation. Express your answer to two significant figures.

You are an astronomer and are searching for planets in other stellar systems for which conditions on the surface of the planets are similar to the Earth. You have identified a candidate star, Tycho1601 that you know has same size to the Sun but 1.4 times the surface temperature of the Sun (our Sun). Around that star there are four planetsrotating around it. You are about to invest valuable telescope time in studying the individual planets which one you start with?A) Planet TychoA located at a distance that is half the distance between our Earth and our Sun.B) Planet TychoB located at a distance that is equal to the distance between our Earth and our Sun.C) Planet TychoC located at a distance that is double the distance between our Earthand our Sun.D) Planet TychoD located at a distance that is ten times the distance between our Earth and our Sun.
A neutron star is a cold, collapsed star with nuclear density. A particular neutron star has a mass twice that of our Sun with a radius of 12.0 km. (a) What would be the weight of a 100-kg astronaut on standing on its surface? (b) What does this tell us about landing on a neutron star?
A star is formed when the gravitational attraction overcomes the pressure due to the gases inside.Thus we can write(in-picture) .... Assuming the ideal gas equation, we can write P = nkT, where n is the number of atoms/volume. Let M and m denote the total mass and the mass of each gas atom. Using the above equation, show that the condition for star formation is that the mass of the star obeys M > MJ, where : (in-picture)
On Dec 5, 2022, scientific history was made at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California when nuclear fusion was achieved when the 192 lasers deposited about 2 Megajoules (MJ) of energy into a frozen pea sized deuterium-tritium pellet and ignited the pellet through nuclear fusion to release 3 MJ of energy. The metric prefix mega means million (10^6). a) How much mass (kg) would be required to release 1 MJ of energy?
Like most spacecraft returning from orbit, the Apollo command module entered the atmosphere at 7.8 km/s. In front of the capsule was a shock front, the leading edge of the shock front we call a bow shock. Let’s consider the conditions as it passes an altitude of 40,000 feet, at 461 miles per hour. 1a) What are the density, pressure, and temperature behind the shock front? 1b) In the frame of the shock, what is the velocity at which the gas approaches the shock? What is the velocity with which the gas leaves the shock? 1c) In the frame fixed on the Earth, what is the velocity of the post- shock gas?
A black hole is a blackbody if ever there was one, so it should emit blackbody radiation, called Hawking radiation. A black hole of mass M has a total energy of MC2, a surface area of 16πG2M2 / c4 and a temperature of hc3 /16π2kGM. Imagine a black hole in empty space, where it emits radiation but absorbs nothing. As it loses energy, its mass must decrease; one could say it "evaporates." Derive a differential equation for the mass as a function of time, and solve this equation to obtain an expression for the lifetime of a black hole in terms of its initial mass.
