A new asteroid rotation period survey has been carried out by using the Palomar Transient Factory (PTF). Twelve consecutive PTF fields, which covered an area of 87 deg2 in the ecliptic plane, were observed in the R band with a cadence of ∼20 minutes during 2013 February 15–18. We detected 2500 known asteroids with a diameter range of 0.5 km ⩽D ⩽ 200 km. Of these, 313 objects had highly reliable rotation periods and exhibited the “spin barrier” at ∼2 hr. In contrast to the flat spin-rate… 

ASTEROID SPIN-RATE STUDY USING THE INTERMEDIATE PALOMAR TRANSIENT FACTORY

Two dedicated asteroid rotation-period surveys have been carried out in the R band with ∼20 minute cadence using the intermediate Palomar Transient Factory (iPTF) during 2014 January 6–9 and February

ASTEROID LIGHT CURVES FROM THE PALOMAR TRANSIENT FACTORY SURVEY: ROTATION PERIODS AND PHASE FUNCTIONS FROM SPARSE PHOTOMETRY

We fit 54,296 sparsely sampled asteroid light curves in the Palomar Transient Factory survey to a combined rotation plus phase-function model. Each light curve consists of 20 or more observations

Asteroid spin-rate studies using large sky-field surveys

Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from

LARGE SUPER-FAST ROTATOR HUNTING USING THE INTERMEDIATE PALOMAR TRANSIENT FACTORY

In order to look for large super-fast rotators, in late 2014 and early 2015, five dedicated surveys covering ∼188 deg2 in the ecliptic plane have been carried out in the R-band, with ∼10 minute

A NEW LARGE SUPER-FAST ROTATOR: (335433) 2005 UW163

Asteroids of size larger than 150 m generally do not have rotation periods smaller than 2.2 hr. This spin cutoff is believed to be due to the gravitationally bound rubble-pile structures of the

BGLS-based method of estimating the rotational periods of asteroids

As the asteroid rotational period is important to the study of the properties of asteroids (e.g., super-fast rotators have structures owing an internal cohesion (rather than being rubble piles

Solar System Science with ESA Euclid

Evaluating Euclid capability to discover SSOs, and measure their position, apparent magnitude, and SED, and estimating how Euclid will constrain the SSOs dynamical, physical, and compositional properties is evaluated.

Confirmation of Large Super-fast Rotator (144977) 2005 EC127

(144977) 2005 EC127 is a V-/A-type inner-main-belt asteroid with a diameter of 0.6 ± 0.1 km. Asteroids of this size are believed to have rubble-pile structure, and therefore cannot have a rotation

Non-Vestoid candidate asteroids in the inner main belt

Context. Most howardite-eucrite-diogenite (HED) meteorites (analogues to V-type asteroids) are thought to originate from the asteroid (4) Vesta. However some HEDs show distinct oxygen isotope ratios
