Of course, they have nothing to do with planets but rather represent late stages in the evolution of low mass stars in which a double shell source (Hydrogen and Helium Burning) around a non-fusing Carbon core is driving the outer layes of the star away, thus revealing a hotter star (the central star of the Planetary nebula). ...

... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...

White dwarfs, the endpoints of stellar evolution for most stars, experience a quieter birth than pulsars. While a pulsar's planetary companions are probably second generation objects, planets around white dwarfs are almost certainly surviving members of original systems, and more closely related to our solar system. ...

... In addition to the planets and their satellites the solar system contains a large number of smaller but interesting objects. There are thousands of known asteroids and comets and undoubtedly many more unknown ones. ... There are also some asteroids whose orbits carry them closer to the Sun than the Earth (Aten, Icarus, Hephaistos). Most comets have highly elliptical orbits which spend most of their time in the outer reaches of the solar system with only brief passages close to the Sun. ...

... 2015 . ... Observations using the Arecibo S-band (2380 MHz, 12.6 cm) planetary radar system started in 1976 and its power and sensitivity were greatly improved with the telescope upgrade and Gregorian-dome installation in the mid-1990s. Below, we show the number of near-Earth asteroids attempted and detected since the radar program resumed in 1998. ... The number of NHATS objects detected with Arecibo similarly jumped in 2012, and 2015 was again a record year, where we detected 23 of these objects. ...

This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...
