SpT F0V

WDS notes

ELODIE archive shows change in radial velocity of about 1 km/s over ~2000 days, too large for M companion?

WDS J07291+3147B, Gliese 274 B

SIMBAD

CPM. Separation ≈ 3 arcsec ≈ 70 AU

Woefully unreferenced

WDS J07291+3147C

Differing proper motion, unrelated

D nearby to C, possibly bound to C. Blah.

WDS J07291+3147E, HIP 36357, Gliese 273.1 (Not to be confused with Gliese 273, Luyten's star)

CPM. Separation ≈ 755 arcsec ≈ 18600 AU

Bound. (0.22 ly! Probably overestimate.)

BY Draconis variable?! ELODIE RV stable so no close comp star, but youth is a possibility. Lick SHK is at about 0.5, comparable to Eps Eri's SHK of ~0.5 = RHK -4.5 or so. So yes, probably young.
