We present the second set of discoveries from Keck Observations in the INfrared of Taurus and Oph Exoplanets And Ultracool dwarfs (KOINTREAU), an adaptive optics survey of youn…
Strongly polarised radio pulses from a new white-dwarf-hosting long-period transient
Sanne Bloot, Harish K. Vedantham, Cees G. Bassa +6
Long-period transients (LPTs) are a new and enigmatic class of objects that produce bright pulsations in the radio, with periods far exceeding those seen in rotationally powered pu…
