B9.5IV Garrison77 (nor anyone else) lists any B9.5IV standards. # Non-standard stars HD 108767 = del CrV = HR 4757 B9V: MK43,Jaschek64(all),Murphy69 B9Vn: Cowley69 B9.5V: Abt81,Gahm83,Houk88,Mora01 *B9.5IV-n: GrayGarrison87 A0: Cannon Mermilliod91: V=2.948+-0.010, B-V=-0.046+-0.005, U-B=-0.079+-0.017. => updated Q-method => E(B-V) = -0.018 (apparently unreddened given the photometric errors) => hence, (B-V)o = -0.046, (U-B)o = -0.079, E(B-V) = Av = 0.00. VanLeeuwen07 plx = 37.55+-0.16 mas => D = 26.6+-0.1 pc. The photometric distance (assuming the star is on the ZAMS) is ~23+-5 pc. Mv = 0.81 and delta(Mv) = -0.23 - hence close to the main sequence. Delta(V)=5.5 binary. So it looks like this this is now a B9.5, and most say dwarf. Teffs: 10162K(Erspamer03), 10580+-400K(Zorec09).
