What is the radius of the sphere you would have to spread them out over if you wanted them to have the same density as the interstellar medium, about 1 atom per cm3? You can look up the mass of an oxygen atom.arrow_forwardOn which edge of the main sequence band on an HR diagram would the zero-age main sequence be?arrow_forward
- Which of the following statements is/are true regarding a nebula? Which of the following statements is/are true regarding a nebula? It is believed that each planet in our solar system began as its own nebula. Over time, a nebula becomes cooler and grows in size. The density of a nebula is greatest at the edges and least in the center. There are no nebulas left in our galaxy because they have all formed stars and planets. Over time, a star will form at the center of a nebula.arrow_forwardH5. A star with mass 1.05 M has a luminosity of 4.49 × 1026 W and effective temperature of 5700 K. It dims to 4.42 × 1026 W every 1.39 Earth days due to a transiting exoplanet. The duration of the transit reveals that the exoplanet orbits at a distance of 0.0617 AU. Based on this information, calculate the radius of the planet (expressed in Jupiter radii) and the minimum inclination of its orbit to our line of sight. Follow up observations of the star in part reveal that a spectral feature with a rest wavelength of 656 nm is redshifted by 1.41×10−3 nm with the same period as the observed transit.

- Absorption lines produced by interstellar gas a. are wider than the lines from stars because the gas is hotter than most stars. b. are more narrow than the lines from stars because the gas has a lower pressure than stars. c. indicate that the interstellar medium contains dust. d. indicate that the interstellar medium is expanding away from the sun. e. indicate nothing; none of the above statements are true.arrow_forwardThe place on the H–R diagram where contracting protostars first become visible is a. the horizontal branch. b. the instability strip. c. the birth line. d. the zero-age main sequence. e. none of the above.arrow_forwardWhy was the nebular hypothesis never fully accepted by astronomers of the day?arrow_forward
