A first expedition to Alpha Centauri (the nearest planetary system) is being planned. Alpha Centauri is 4.3 ly away. Answer the following 5 questions below asking you about the details of this expedition.
- My question is What does an astronomer need to understand the fundamentals of to be able to calculate the age of the universe?Match each characteristic below to the appropriate stellar end state. (Select W-White dwarf, N-Neutron star, B-Black hole. If the first is W and the rest N, enter WNNNNNNN). A) Size defined by its Schwarzschild radius. B) Typically about the size of Earth. C) Usually has a very strong magnetic field. D) In a binary system it can explode as a supernova. E) Supported by electron degeneracy pressure. F) Sometimes appears as a pulsar. G) Viewed from afar, time stops at its event horizon. H) Has a mass no greater than 1.4 solar-masses.1.) How far, in parsecs, is an object that has a parallax of 1 arc second? How far is it, in light years? 2.) How far in parsecs, is an object that has a parallax of 0.1 arc-seconds? How far is it, in light years?
- An eclipsing binary will a. be more luminous than a visual binary. b. always be a spectroscopic binary. c. give off most of its light in the infrared. d. show a constant Doppler shift in its spectral lines. e. show two stars with variable proper motion.3- Consider a binary star system in which the two stars are seen to be 1.50" apart. Determine the actual physical separation of those stars (in AU) if this binary system is located 9.50 1.y. from us.Astronomy help What does each number (6-10) represent?
