Abstract
An isothermal layer suspended from a surface is gravitationally (Rayleigh-Taylor) unstable. We find that, when a vertical temperature difference ΔT above a critical value (ΔT)c is imposed across the liquid-gas layer system (heated from below), the restoring force provided by the temperature-dependent surface tension (thermocapillarity) can stabilize the layer. Our measurements of the most unstable wave number for ΔT<(ΔT)c agree well with our linear stability analysis. The instability occurs at long wavelengths: the most unstable wavelength at (ΔT)c is infinite.
