Astronomy and astrophysics

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.

    High-angular-resolution observations of 1.3 mm continuum and H30α recombination line emission identify a binary star system in formation, with protostars apparently separated by 180 au. The velocity difference between the two protostars constrains the orbital period and total mass of the system.

    Jupiter’s magnetic field can affect the circulation of the internal ocean of Europa and possibly of other Jovian moons by generating a Lorentz force in the ocean’s salty water. Such a force creates an equatorial jet that affects the ocean’s dynamics and acts as a torque on Europa’s ice shell, possibly affecting its surface features.
