All of this suggests that getting
into orbit around a star, preferably while a grad student or postdoc, is an increasingly important career - building strategy.

When Kepler launched
into orbit in 2009 to survey a patch of sky containing some 150,000
stars, one of its primary goals was to find mirror Earths, worlds about the same size as our own in approximately 365 - day
orbits around sunlike
stars.
Captured by Kepler's digital sensors, transformed
into bytes of data, and downloaded to computers at NASA's Ames Research Center near San Francisco, the processed starlight slowly revealed a remarkable story: A planet not much bigger than Earth was whipping
around its native
star at a blistering pace, completing an
orbit — its version of a «year» — in just over 20 hours.
Around younger
stars, however, many of these newly formed objects have yet to settle
into stately
orbits and routinely collide, producing enough rubble to spawn a «second - generation» disk of debris.
Now, Hippke and Heller show that a combination of the
stars» gravity and radiation pressure from their photons can bring the craft
into a stable
orbit around one of the
stars, then
around the tantalising planet (Astrophysical Journal Letters, doi.org/bx8t).
The team used the carbon monoxide study as a guide to expand the RV technique
into the infrared to determine the
orbit of tau Boo b itself
around its
star, and added further analysis of the light shifts via spectroscopy — an analysis of the light's spectrum.
Those remnants went
into orbit around the white dwarf — much like the rings
around Saturn, Zuckerman said — before eventually spiraling onto the
star itself, bringing with them the building blocks for life.
But if approved, K2 will be looking at a much more diverse region of sky with a wide range of astronomical and astrophysical phenomena: planets with short
orbits around cooler
stars (which, if in their
star's habitable zone, could still harbor water); young, still - forming proto -
stars, which could provide insight
into star and planet formation; and supernovae and galaxy clusters.
However, the
stars will be thrown
into different
orbits around the new galactic center.
So - called circumbinary planets — those planets that
orbit around a binary
star, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org prepri

The numerous galaxy collisions literally tear some galaxies apart and scatter their
stars into wide
orbits around the newly created large galaxies, which should give the galaxies a faint background glow of stellar light.
Although the cluster dissolved over the past 4.6 billion years with the dispersal of the Sun's sibling
stars into the surrounding the Milky Way, the
stars should have remained on a similar
orbit around the galactic center.
