Solar Neighborhood (10 ly)


100 light-years

Solar Neighborhood (100 ly) — Draft complete to 30 ly

Non-Main Sequence

Giants and Subgiants (100 ly) — Draft complete to 50 ly
Subdwarfs (100 ly) — Draft complete to 30 ly — Population II stars: old, heavy element-deficient stars
White Dwarfs (100 ly) — Draft complete to 30 ly — Stellar remnant of stars that were originally at most ten times as massive as the Sun
Brown Dwarfs (100 ly) — Draft complete to 30 ly — Substellar

Main Sequence

Hot (OBA) Stars (100 ly) — Draft complete to 50 ly — Surface temperatures are 7 500 K or higher, as compared to 5 800 K for the Sun
Moderate (FGK) Stars (100 ly) — Draft complete to 50 ly — The most inclusive set of stars that could potentially host Earth-like planets
Red (ML) Dwarfs (100 ly) — Draft complete to 30 ly — Surface temperatures are below 3 700 K

Focused Surveys

Solar-Type Stars (100 ly) — Draft complete to 50 ly — Main sequence stars with B-V color index of 0.48—1.00 (roughly F6 V through K3 V)
Solar Analogues (100 ly) — Draft complete to 50 ly — Main sequence stars with temperature 5 200—6 300 K, metallicity 0.5—2 solar, and no close companion
Solar Twins (100 ly) — Main Sequence stars with temperature 5 720—5 830 K, metallicity 0.89—1.12 solar, no companion, and an age of 3.5—5.6 Ga

Habstars (100 ly) — Draft complete to 30 ly — Stars in Turnbull & Tarter's HabCat, notable because it focuses on potential habitability (without arbitrarily excluding red dwarfs)

Moderate (FGK) Habstars (100 ly) — Draft complete to 30 ly — Habstars that could host Earth-like planets (as opposed to tidally locked planets, or non-C/H₂O life)
Solar-Type Habstars (100 ly) — Draft complete to 30 ly — Habstars that are more Sun-like
Solar Analog Habstars (100 ly) — Draft complete to 30 ly — Habstars that are especially Sun-like
Solar Twin Habstars (100 ly) — The most Sun-like of all
