SUMMARY

The discussion focuses on identifying G2 main sequence dwarf stars located within a 10 to 50 light-year radius from Earth for a science fiction novel. Key stars mentioned include Epsilon Eridani (K2V), Tau Ceti (G8V), Epsilon Indi (K5V), 82 Eridani (G8V), and Eta Cassiopeiae A (G2V). The user, MD Watson, seeks to incorporate scientifically plausible celestial bodies into their narrative, emphasizing the importance of using real stars for world-building. Additionally, the "HabCat" catalog, developed by SETI researchers, is recommended for further exploration of potentially habitable stars.

PREREQUISITES
  • Understanding of stellar classifications, specifically G2 and K-type stars.
  • Familiarity with light-year measurements and their significance in astronomy.
  • Knowledge of protoplanetary disks and their relevance to planetary formation.
  • Basic research skills to utilize astronomical catalogs like the Hipparcos catalog and HabCat.
NEXT STEPS
  • Research the characteristics of Epsilon Eridani and its protoplanetary disk.
  • Investigate the potential for habitable planets around Tau Ceti.
  • Explore the Hipparcos catalog for additional nearby stars.
  • Learn about the HabCat and its criteria for identifying potentially habitable stars.
USEFUL FOR

Writers, especially those in the science fiction genre, astronomers, and educators interested in the intersection of real astronomy and creative storytelling will benefit from this discussion.

I'm a writer working on my first novel. The genre is science fiction and I'm trying to keep the science part of it as close to the realm of possibility as I can.

The setting is in a smaller system about 10 to 50 light years of our system.
Can someone name a star and its location that is of the same type (G2, main sequence, dwarf) found within that 10 to 50 LY radius? I don't think Sirius or Alpha Centauri will work. I'm more than willing to research several stars located within this range; Even binaries if one star of the binary fits the criteria.
Until we get good enough to find other habitable planets I feel good about "fictionizing" planets orbiting a real star that can be found on a chart.

Thanks for your research,

MD Watson

If you Google for "nearest stars" you'll get some good lists that also have the spectral type. A couple are:

Epsilon Eridani (K2V - which actually has planets, but also a decent protoplanetary disk)
Tau Ceti (G8V)
Epsilon Indi (K5V)
82 Eridani (G8V)
Eta Cassiopeiae A (G2V - the companion is a K7V out on a 480 year orbit)

You might also look up "HabCat" on Google too. It was made by SETI people out of the Hipparcos catalog, and is a catalog of nearby stars that could potentially have habitable planets.
