Multitechnique testing of the viscous decretion disk model I. The stable and tenuous disk of the late-type Be star $\beta$ CMi

TL;DR: In this article, a parametric VDD model with radial density exponent of 3.5, which is the canonical value for isothermal flaring disks, is found to explain observables typically formed in the inner disk, while observables originating in the more extended parts favor a shallower, $n$ = 3.0, density falloff.

TL;DR: In this article, Carcariofi et al. modeled the observed spectral energy distribution (SED) covering the interval from ultraviolet to radio using the Monte Carlo radiative transfer code HDUST and obtained new multi-band cm flux density measurements of ψ Per from the enhanced VLA.

TL;DR: In this paper, the authors detect periodic Doppler shifts in the wings of the H$\alpha$ line with a period of 170 d and an amplitude of 2.25 km s$^{-1}, consistent with a low-mass binary companion.
