Key Points: atmosphere of exoplanets and its magnetic field

 Ohmic heating: The variations of the time varying magnetic field can induce currents in the upper atmosphere of some exoplanets, which dissipate and locally heat it up; it is called ohmic heating.Equation for Induction and heating within a planet (which is described from ohm’s law, Ampere law,...

Overview: Study of magnetization temperature in ferromagnetic crystals

EuO and EuS Materials are used in study. As per Weiss mean field approximation (MFA), below certain critical temperature(Tc) ferromagnetic materials have spontaneous magnetization — i.e., a sizable macroscopic magnetic moment even in the absence of an external magnetic field. The effective field acting...

Summary of article about Transit Simulator for Objects Orbiting Stars

The quadratic limb darkening law was used in study. It is a model that describes the variation in the intensity of a star's photosphere as a function of the viewing angle.I(μ) is the intensity of the star at u = cos (theta), i.e., the cosine of the angular separation of a point with respect to the center...

Summary of article: Ultrasonic Atomization for Liquid Metals

 Ultrasonic atomization is a process that uses ultrasound waves to create tiny droplets from a liquid.As per study Particle diameter d isρ and σ are respectively the density and surface tension of the atomized fluid andf is a vibration frequency. Particle diameter also depends on Weber, Ohensorge...

Summary of Article: melanin as a material for solar light absorbers

 The infrared transmission spectra, Optical Density spectra, atomic force microscopy is used in study.As per Lambert-Beer lawd is the melanin film thickness, ln(Ub/Us)  is measured from Optical Density.The absorption coefficient decreases to ~ 10^4 cm−1 in the visible and near infrared region....

Overview of article: Study of magnetic field change in Sun

Parker Solar Probe(PSP) has discovered the prevalence of switchbacks (SBs)-switchbacks are sudden reversals in the magnetic field in the solar wind. The researchers used the Adaptively Refined Magnetohydrodynamics Solver (ARMS) method.Solar wind velocity has a similar behavior characterised by a logarithmic...

Key Points of Study of Deformation of the ice front by particle

As the freezing front approaches the droplet, the temperature on one side of the droplet is different than on the other side. That causes a difference in surface tension which occurs as a force, thermal Marangoni force.As per observation in solidification front of ceramic Zirconia and polystyrene (PS) particle, If the particle is more thermally conductive, heat flows through it, and the ice front...

Summary of article: V2O3 metallic property at external V, I

 Topological defects: These are imperfections in the structure of a material that arise when its internal arrangement (lattice or order parameter) cannot be perfectly aligned.Resistive switching is a sudden transition between insulating and metallic states triggered by an electric field.When V2O3 temperature is changed from high to low, the structure changes from rhombohedral shape to less symmetric...
