The linear stage of hydrodynamic instability of a laminar premixed flame propagating in a Hele-Shaw cell is investigated. Our theoretical model takes into account momentum and heat losses, temperature-dependent transport coefficients, and the continuous internal structure of the flame front. The dispersion relation is obtained numerically as a

The near-Earth object (NEO) population is composed of asteroids and comets that have orbits close to the Earth. This vicinity to the Earth gives us some advantages, because this population is the most accessible vestige from the building blocks that formed the Solar System, for spacecrafts, and for detailed observations from ground-based facilities
