Softening and instability evolution of strip coal pillar under water immersion in goaf [PDF]
Scientific ReportsThe softening and instability of the coal pillar caused by water immersion is the primary factor contributing to water inrush in the goaf of the same layer.

Convective effects and the RR lyrae instability strip [PDF]
Symposium - International Astronomical Union, 1984 The effects of nonlinear, nonlocal, diffusive convection have been included in the structure equations of pulsational hydrodynamic analyses of a series of RR Lyrae models. We find a well-defined red edge of the unstable region that depends on mode of pulsation.

The Cephei instability strip [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We carried out a series of linear stability analyses of the radial and low-degree non-radial p modes for stellar models with initial masses of . The stellar models were computed by using convective overshoot distance , 0.25 and 0.40 HP. Our numerical results show that the β Cephei instability strip forms a horn-shaped region pointing upwards near the ...

Instability strip for pre-main-sequence stars [PDF]
Communications in Asteroseismology, 2007 We apply the Time Dependent Convection (TDC) treatment presented in Grigahcene et al. (2005) to the study of Pre-main sequence pulsating stars. The stabilization of the p-modes at the red edge of the Instability Strip (IS) is obtained by our models. The theoretical IS obtained with Mixing Length (ML) parameter α =1.8 is compared to observations and a ...

The First Theoretical γ Doradus Instability Strip [PDF]
International Astronomical Union Colloquium, 2004 AbstractWe present the first theoretical γ Doradus instability strip. We find that our model instability strip agrees very well with the previously established, observationally based, instability strip of Handler & Shobbrook (2002). We stress, as in Guzik et al. (2000), that the convection zone depth plays the major role in the determination of our

Non-Cepheids in the Instability Strip [PDF]
International Astronomical Union Colloquium, 1985 AbstractThe question of whether non-Cepheids populate the cepheid instability strip has been the subject of much recent interest. Several investigators (see especially Fernie and Hube 1971 and Fernie 1976) have concluded that indeed there are an appreciable number of objects not presently recognized as Cepheids within the strip, though both the size ...

The Instability Strip of M3 [PDF]
International Astronomical Union Colloquium, 2000 We present new multicolour CCD photometry of the central part of the globular cluster M3, mapping the precise position of ~120 RR Lyrae stars (RRab, RRd, RRc) on the horizontal branch (HB). The location of the double-mode variables (RRd) is in perfect agreement with recent theoretical results.
