- A distant F0 star is 6.3 times less bright than a nearer F0 star which has a parallax of 0.2 arcsec. Calculate its distance in parsecs.How far away is the star Spica, whose parallax is 0.0130?International Astronomical Union reported on 24 Feb 1987: An object was discovered on Feb. 24.37 UT (position R.A. = 5h35m.8, Decl. = -69 18'), obtained m = 4.8 on Feb. 24.454 UT. This object proved to be the most famous supernova (SN) in the 20th Century and the brightest visible from Earth since 1604. It is classified as a SN of the type Il in the Large Magellanic Cloud (SN1987A). Its brightness peaked in May 1987, with an apparent magnitude of m = 2.8. a) Find the absolute magnitude M of the SN1987A at maximum. Distance of the LMC is 51,400 pc. b) The progenitor (before SN explosion) star was a blue supergiant of the apparent magnitude m = 12.8. How much brighter (in terms of flux density) this SN was at maximum compared to the progenitor star. Find the ratio FSN / Ebefore
- What is the parallax of a star that is 150 pc from Earth?Calculate by how many times Betelgeuse is brighter than the Sun, if its parallax is 0.006 arcsec, and its apparent magnitude is m = +.5. Can you first use the parallax to calculate the distance and then use the magnitude-distance formula to find the absolute magnitude of Betelgeuse and finally, compare it to the absolute magnitude of the Sun which is -26,74 because other experts used other methods and the answer was not correct.A nearby star has a parallax of 0.317 arcseconds. How long does it take the light from this star to reach us?
- 17 Which of the following statements about parallax is not true? A You can demonstrate parallax simply by holding up a finger and looking at it alternately from your left and right eyes. B C D The existence of stellar parallax is direct proof that Earth orbits the Sun. Measurement of stellar parallax allows us to determine distances to nearby stars. The technique of stellar parallax was used by Hubble to determine that the Andromeda Galaxy (M 31) is about 2 million light-years away. Ancient astronomers were unable to measure parallax and used the absence of observed parallax as an argument in favor of an Earth-centered universe.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?If the mass of a star is 9.94 10^30 kg then what is Kepler's constant for that star?Reminder k = ( T^2 / R^3 )
