The study's authors believe that the YORP effect is the more likely explanation for this new discovery.
This spin-up process is called the YORP effect (for Ivan Yarkovsky, John O'Keefe, Vladimir Radzievsky, and Stephen Paddack).
Professional astronomers recently discovered the YORP effect (standing for Yarkovsky, O'Keefe, Radzievskii, and Paddack).
For some time, professional astronomers had been hoping to detect a theoretically-predicted phenomenon called the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, that the spin rate of non-spherical asteroids should change over time as a result of the pressure exerted on them by the sunlight falling on their surfaces.
An asteroid's rotation and acceleration are influenced by sunlight - the "YORP Effect." If the YORP effect causes an asteroid to rotate faster than one revolution in 2.2 hours, it will break apart.
Researchers invoked the YORP eflect, which can make a small body gradually spin up or slow down as it absorbs sunlight and reradiates it as heat.
This phenomenon is named the Yarkovsky-O'Keefe-Radzievskii-Paddick effect after its discoverers, or YORP for short.
