Lava worlds belong to a class of short orbital period planets reaching dayside temperatures high enough melt their silicate crust. Theory predicts that the resulting lava oceans outgas volatile components, attaining equilibrium with overlying vapour. This creates tenuous, silicate-rich atmosphere may be confined permanent planet. The James Webb Space Telescope (JWST) will provide much needed se...

The study of the behavior of sessile droplets on solid substrates is not only associated with common everyday phenomena, such as the coffee stain effect, limescale deposits on our bathroom walls , but also very important in many applications such as purification of pharmaceuticals, de-icing of airplanes, inkjet printing and coating applications. In many of these processes, a phase change happen...

In this paper we obtain the black hole metric from a semiclassical analysis of loop quantum black hole. Our solution and the Schwarzschild one tend to match well at large distances from Planck region. In r = 0 the semiclassical metric is regular and singularity free in contrast to the classical one. By using the new metric we calculate the Hawking temperature and the entropy. For the entropy we...
