KUI 44 20 Leo. B is a Delta Scuti-type variable, DG Leo. Cou1955c
A is a double-lined spectroscopic binary, P=4.147d.
Radial velocity is variable, amplitude 30 km/sec (Plaskett). Two
spectra are visible (Shajn & Albitzky) Dan1952
Lampens et al. derive effective temperatures for the Aa, Ab, and B Lmp2008
components of 7470+/-220, 7390+/-220, and 7590+/-220 K, respectively.
Relative fluxes from these three late-A stars are similar: 32+/-2,
31+/-2, and 37+/-2%.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 4.95 +/- 1.87, 4.29, and 1.82 Msun, respectively. Mlk2012
