  • Simulations of Milky Way-like star clusters show that most (>57%) stars form in multiples. Approximately 75% of binaries are gravitationally bound from the birth of the secondary, and ~40% of (eventual) single stars originated in a multiple system.

  • Direct imaging has revealed the existence of a large planet orbiting a binary system that contains the most massive planet-hosting stars detected so far. The discovery challenges existing models for how planets and stars form.

  • High-resolution astronomical observations of a nearby molecular gas cloud have revealed a quadruplet of stars in the act of formation. The system is arguably the youngest multiple star system detected so far. See Letter p.213

  • A very cold and/or extremely reddened protoplanet in the disk around MWC 758 has been detected in images and with spectroscopy. MWC 758c is responsible for driving the disk’s spiral arm patterns. The protoplanet orbits at a projected separation of ~100 au and is one of the youngest giant planets known.

  • 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.
