Describe the protoplanet nebular model of the origin of the solar system. Which part or parts of this model seem least credible to you? Explain. What information could you look for today that would cause you to accept or modify this least credible part of the model?
The description of the protoplanet nebular model of the solar system and the part of the model which seem credible. Also, the information that can lead to the acceptance of the least credible part of the model.
Answer to Problem 1CQ
A protoplanet is the earliest stage in the formation of a planet which involves three stages: (A) The formation of elements heavier than hydrogen and creation of large clouds of dust and gases, (B) The beginning of formation of large and slowly rotating nebula from the remaining gas, dust, elements and compounds of chemical compounds and (C) It begins when protosun establish as a star after undergoing an initial flare-up which blasted away most of the hydrogen and helium gas around the inner planets.
The information regarding the reason for the formation of the planets, the reason for the accretion disk, and reason for the inner planets being rocky when the outer planets are gaseous can lead to the acceptance of the least credible part of the model.
Explanation of Solution
A protoplanet is the earliest stage in the formation of a planet. The model can be considered in stages, which are not really a part of the model but a convenient way for better understanding. It involves three stages which are given below.
Stage A: It is the stage of formation of the solar system which consists of the formation of the elements heavier than hydrogen. It involves the creation of large clouds of dust and gases which rotates slowly from the supernova of earlier stars.
Stage B: It involves the beginning of formation of large and slowly rotating nebula which is larger than the solar system from the remaining gas, dust, elements and compounds of chemical compounds when pulled into the center which then clumps together from numerous collisions.
Stage C: This stage begins when the protosun establish as a star after undergoing an initial flare-up which blasted most of the hydrogen and helium gas around the inner planets. The planets are sometime heated early in their formation so that the heavier elements are pulled to the center. Early atmosphere is formed from gases from the interiors of the planets.
There are many parts of the model which may not seem credible. The information regarding the reason for formation of the planets, the reason for the accretion disk, and reason for the inner planets being rocky when the outer planets are gaseous can lead to acceptance of least credible part of model.

- Describe the solar nebula, and outline the sequence of events within the nebula that gave rise to the planetesimals.arrow_forwardWhat can we learn about the formation of our solar system by studying other stars? Explain.arrow_forwardKepler-444 is one of many stars with terrestrial planets that is over 10 billion a) What do you think the spectral type of Kepler-444 might be? b) How do stars of this spectral type end their lives? c) If evolution followed a similar course on a habitable pranet around a star similar to Kepler-444, it would be 5 billion years more advanced than we are. Let’s try to project our future and see what happens. In particular, suppose our civilization gets motivated enough to colonize another planet. Kepler indicates that most stars have potentially habitable (and colonizable) planets, so roughly how far away is the typical “nearest" planet? d) The New Horizons probe on its way to Pluto took 9 years to travel 30 AU. If we could send colony ships with the same average speed, roughly how long would it take to reach the typical nearest planet? уears old.arrow_forward

- H5. 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.
