A millimeter Continuum Size–Luminosity Relationship for Protoplanetary Disks [PDF]
, 2017 We present a survey at subarcsecond resolution of the 340 GHz dust continuum emission from 50 nearby protoplanetary disks, based on new and archival observations with the Submillimeter Array.

Size–Luminosity Relations and UV Luminosity Functions at z = 6–9 Simultaneously Derived from the Complete Hubble Frontier Fields Data [PDF]
, 2017 We construct z ∼ 6–7, 8, and 9 faint Lyman break galaxy samples (334, 61, and 37 galaxies, respectively) with accurate size measurements with the software glafic from the complete Hubble Frontier Fields (HFF) cluster and parallel fields data.

K-corrections: an Examination of their Contribution to the Uncertainty of Luminosity Measurements
The Open Journal of Astrophysics, 2016 In this paper we provide formulae that can be used to determine the uncertainty contributed to a measurement by a K-correction and, thus, valuable information about which flux measurement will provide the most accurate K-corrected luminosity. All of this

Folia Horticulturae, 2020 Terrestrial plants are constantly exposed to multiple environmental signals that influence their metabolism. Among these signals, nitrogen (N) nutrition and light affect importantly diverse metabolic and physiological processes. Herewith the effects of N

On the Luminosity of Young Jupiters [PDF]
The Astrophysical Journal, 2007 Traditional thermal evolution models of giant planets employ arbitrary initial conditions selected more for computational expediency than physical accuracy. Since the initial conditions are eventually forgotten by the evolving planet, this approach is valid for mature planets, if not young ones.

REIONIZATION AFTER PLANCK: THE DERIVED GROWTH OF THE COSMIC IONIZING EMISSIVITY NOW MATCHES THE GROWTH OF THE GALAXY UV LUMINOSITY DENSITY [PDF]
, 2015 Thomson optical depth τ measurements from Planck provide new insights into the reionization of the universe. In pursuit of model-independent constraints on the properties of the ionizing sources, we determine the empirical evolution of the cosmic ...

Nature, 1899 THE communication of Mr. J. Burke to the British Association, on the luminosity of sugar (NATURE, vol. lviii. p. 533) recalls to my mind an illustration on the large scale of the same interesting phenomenon.

THE PROTOSTELLAR LUMINOSITY FUNCTION [PDF]
The Astrophysical Journal, 2011 The protostellar luminosity function (PLF) is the present-day luminosity function of the protostars in a region of star formation. It is determined using the protostellar mass function (PMF) in combination with a stellar evolutionary model that provides the luminosity as a function of instantaneous and final stellar mass. As in McKee & Offner (2010)
