if a transit depth of 0.00001 can be detected with the Kepler spacecraft, what is the smallest planet that could be detected around a 0.4 Rsun M dwarf star? Give the radius in terms of the radius of the Sun.
transit depth is the ratio of surface area of planet and the star
transit depth =
where Rp = radius of planet
Rs= radius of star
Thus
transit depth =

- (Astronomy) Supernova Ejection Times. Observations show that the gas ejected from SN 1987A is moving at about 10,000 km⁄s. How long will it take to travel one astronomical unit in hours? (Note that 1 AU equals 1.5 × 108 km)What are the two possibilities for the final state of a close, massive binary system?(Astronomy) Binary Pulsar. Part A: Use the orbital period 27 min for the binary pulsar (two neutron stars orbit each other) to find the orbital separation of the pair in AU and solar radii. Assume a neutron star's mass is 3 solar masses. (Hints: Use the version of Kepler's third law for binary stars.) Part B: Is this system orbiting closer or further than Mercury is to the Sun?
- using the center-of-mass equations or the Carter of Mass Calculator (under Binary-Star Basics, abova), you will investigate a specific binary star system. Assume that Star 1 has m, 3.2 solar masses, Star 2 has m,-0.9 solar masses, and the total separation of the two (R) is 34 All (One AU is Earth's average distance from the Sun) (2) What is the distance, d. (In Au) from Star 1 to the center of mass? AU (b) What is the distance, dy On Au) from Star 2 to the center of mass AU ( what is the ratio of d, tod?. The radius of the nebula is about 0.401 light-years. The gas is expanding away from the star at a rate of about 37 kilometers/second . Considering that distance = velocity x time, calculate how long ago the gas left the star if its speed has been constant the whole time. Make sure you use consistent units for time, speed, and distance. Answer in years.How do the spectra of H II regions differ from the spectra of reflection nebulae? Why?
- 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 )The NASA Kepler mission detected a transiting planet that blocks 1.3% of the stars light and the host star has a radius 82% of the Sun's radius (the Sun has a radius of 700,000 km) what is the radius of the exosolar planet in km?Why are we unlikely to find Earth-like planets around halo stars in the Galaxy? A. Halo stars formed in a different way from disk stars. B. Planets around stars are known to be extremely rare. C. Halo stars formed in an environment where there were few heavy elements to create rocky planets. D. Halo stars do not have enough mass to hold onto planets. Is the answer C? Since halo stars are formed early when the galaxy consisted of mainly hydrogen and helium, there are no heavier elements available to create Earth-like planets so just halo stars are formed? Thanks!
- What is the escape velocity (in km/s) from the surface of 1.1 M neutron star? (hint: Use the formula for the escape velocity Ve = 2GM/R ; make sure to express quantities in United of meters, kilograms, and seconds. Assume a neutron has a radius of 11 km and assume the mass of the sun is 1.99 x10^30 kg.) 1.1 M neutron Star = _________ km/s 3.0 neutron Star = __________ km/swhy do dark streaks appear in visible light images of the Trifid nebula, but appear bright in an infared imageConsider a neutron star as a very dense sphere of matter. Assuming that the star has a mass of 1*(mass of sun) and a radius of 0.05*(radius of sun), then how much would a 85.1 kg person weigh on the surface of this star? (enter your answer in Newtons). See the test reference sheet for applicable constants. HINT: Remember what we learned about the force of gravity and the gravitational field (Ch. 13 of the textbook)
