MHD Powell–Eyring nanofluid motion with convective surface condition and Dufour–Soret impact past a vertical plate: Lie group analysis

Partial Differential Equations in Applied Mathematics, 2022
The formerly neglected impact of the convective surface condition and the Soret–Dufour effect on a Powell–Eyring fluid over a vertical plate is brought to light in the present study.

The cool end of the DZ sequence in the SDSS

, 2010
We report the discovery of cool DZ white dwarfs, which lie in the SDSS (u-g) vs. (g-r) two-color diagram across and below the main sequence. These stars represent the extension of the well-known DZ sequence towards cooler temperatures.Comment: To appear ...

Hydrogen delivery onto white dwarfs from remnant exo-Oort cloud comets

, 2014
The origin of trace hydrogen in white dwarfs (WDs) with He-dominated atmospheres is a long-standing problem, one that cannot satisfactorily be explained by the historically-favoured hypothesis of accretion from the interstellar medium.

A continuous low star formation rate in IZw 18 ?

, 2000
Deep long-slit spectroscopic observations of the blue compact galaxy IZw 18 obtained with the CFH 3.6 m Telescope are presented. The very low value of oxygen abundance previously reported is confirmed and a very homogeneous abundance distribution is ...

Timoshenko Beam Model for Lateral Vibration of Liquid-Phase Microcantilever-Based Sensors [PDF]

, 2013
Dynamic-mode microcantilever-based devices are potentially well suited to biological and chemical sensing applications. However, when these applications involve liquid-phase detection, fluid-induced dissipative forces can significantly impair device ...

Cross-Diffusion Effects on the Onset of Double Diffusive Convection in a Couple Stress Fluid Saturated Rotating Anisotropic Porous Layer

Journal of Applied Fluid Mechanics, 2016
In this paper, we have investigated the onset of double diffusive convection (DDC) in a couple stress fluid saturated rotating anisotropic porous layer in the presence of Soret and Dufour effects using linear stability analyses which is based on the ...

A Spitzer Space Telescope Study of the Debris Disks around four SDSS White Dwarfs [PDF]

, 2012
We present Spitzer Space Telescope data of four isolated white dwarfs that were previously known to harbor circumstellar gaseous disks. IRAC photometry shows a significant infrared excess in all of the systems, SDSS0738+1835, SDSS0845+2257, SDSS1043+0855

A study on precise estimation of laminar burning velocity of lean hydrogen-air premixed flame (Effect of species diffusion models)

Mechanical Engineering Journal
Effects of species diffusion models on the laminar burning velocity SL of lean hydrogen-air premixed flame are investigated by performing one-dimensional numerical simulations of lean hydrogen-air premixed flames at an equivalence ratio of 0.5.
