Web21 de ago. de 2002 · Combining this result with the stellar mass-to-light ratio prediction of Bell & de Jong (2001)[log(M *,disc /L K,disc)∝0.45(B-R)], and neglecting differences between K and K′, would imply that the logarithm of the stellar-to-dynamical mass ratio must increase as discs become redder, varying as 1.70±0.28(B-R). WebSimilarly, constraints on the stellar mass to light ratio from kinematics have suggested a similar result (e.g. Auger et al., 2010; Treu et al., 2010; Spiniello et al., 2011; Cappellari et al., 2012, 2013; Brewer et al., 2012; Dutton et al., 2013; Tortora et al., 2013), though we note that increased mass to light ratios can result from both bottom-light and bottom … tree tapestry wall hangings

"In astrophysics and physical cosmology the mass-to-light ratio, normally designated with the Greek letter upsilon, ϒ, is the quotient between the total mass of a spatial volume (typically on the scales of a galaxy or a cluster) and its luminosity. These ratios are often reported using the value calculated for the Sun as a baseline ratio which is a constant ϒ☉ = 5133 kg/W: equal to the solar mass M☉ divided by the solar luminosity L☉, M☉/L☉. The mass-to-light ratios of galaxies and clusters are … " - Mass to light ratio calculator
