Star Trek: Dilithium (Li 2) exists (two covalently bonded lithium atoms); but something else is referred to in fiction. In Star Trek, dilithium occurs in crystal form and serves as a controlling agent in the matter-antimatter reaction cores used to power the faster-than-light warp drive. In the original series, dilithium crystals are rare and ...
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
This top-category page is for specific stars. For groupings of stars, see the sub-category Stellar groupings; For multi-star systems, see the sub-category Star systems.
There is no specific velocity that is considered high, but the proper motion article notes that the majority of stars have a proper motion of 0.01 arc-seconds per year. Note that the closer a star is to earth, the faster it will appear to travel in arc-seconds per year for a given "real" velocity; therefore, the PM values here are apparent ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
The Guide Star Catalog (GSC), also known as the Hubble Space Telescope, Guide Catalog (HSTGC), is a star catalog compiled to support the Hubble Space Telescope with targeting off-axis stars. GSC-I contained approximately 20,000,000 stars with apparent magnitudes of 6 to 15. GSC-II contains 945,592,683 stars out to magnitude 21.
The stars of GG Tauri A are closer to the ring on the northern side (where the streamer is) than the southern side. [29] Finally, although there is not much gas falling into the inner disks, the accretion rate of gas has been measured to be ~ 6 × 10 −8 M ☉ yr −1 which is at least the rate of accretion from the inner disks to the stars ...
