Planet Occurrence Rate Density Models Including Stellar Effective Temperature [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 2018
We present planet occurrence rate density models fit to Kepler data as a function of semimajor axis, planetary radius, and stellar effective temperature.

Results of a phenological study of the European larch (Larix decidua Mill.) growing in a mixed stand

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
This paper presents an evaluation of the onset and duration of phenological stages of the European larch (Larix decidua Mill.) growing in a mixed stand in Drahanská vrchovina highlands.

Rapidity and Energy Dependencies of Temperatures and Volume Extracted from Identified Charged Hadron Spectra in Proton–Proton Collisions at a Super Proton Synchrotron (SPS)

open access: yesEntropy, 2023
The standard (Bose–Einstein/Fermi–Dirac, or Maxwell–Boltzmann) distribution from the relativistic ideal gas model is used to study the transverse momentum (pT) spectra of identified charged hadrons (π−, π+, K−, K+, p¯, and p) with different rapidities ...

HOW TO CONSTRAIN YOUR M DWARF: MEASURING EFFECTIVE TEMPERATURE, BOLOMETRIC LUMINOSITY, MASS, AND RADIUS [PDF]

open access: yes, 2015
Precise and accurate parameters for late-type (late K and M) dwarf stars are important for characterization of any orbiting planets, but such determinations have been hampered by these stars’ complex spectra and dissimilarity to the Sun.

Predicting Maximum Effective Temperatures and Thermal Gradients for Steel I-Girder in Canadian Climate Regions

open access: yesApplied Sciences, 2023
The constant fluctuation of thermal loads on steel members, especially during construction, causes non-uniform distributions of temperatures, resulting in possible constructional and structural defects leading to unfavorable thermally induced responses ...

Empirical photometric calibration of the Gaia Red Clump: colours, effective temperature and absolute magnitude [PDF]

open access: yes, 2017
Gaia Data Release 1 allows to recalibrate standard candles such as the Red Clump stars. To use those, they first need to be accurately characterised. In particular, colours are needed to derive the interstellar extinction.

Determination of the Real Loss of Power for a Condensing and a Backpressure Turbine by Means of Second Law Analysis

open access: yesEntropy, 2009
All real processes generate entropy and the power/exergy loss is usually determined by means of the Gouy-Stodola law. If the system only exchanges heat at the environmental temperature, the Gouy-Stodola law gives the correct loss of power.

Hyperbolic heat conduction, effective temperature, and third law for nonequilibrium systems with heat flux. [PDF]

open access: yesPhysical Review E, 2017
Some analogies between different nonequilibrium heat conduction models, particularly random walk, the discrete variable model, and the Boltzmann transport equation with the single relaxation time approximation, have been discussed. We show that, under an
