A quadrillion previously unnoticed small bodies beyond Neptune have been spotted as they dimmed X-rays from a distant source. Models of the dynamics of debris in the Solar System's suburbs must now be reworked.Solar System minnowsScorpius X-1 (Sco X1) has an important place in the history of astronomy as, apart from the Sun, it was the first cosmic X-ray source ever detected. It now has a new claim to fame: small but significant dips in its X-ray light curves obtained by the Rossi X-ray Timing…

Monodisperse Particles of Bifunctional Periodic Mesoporous Organosilica
Monodisperse particles of periodic mesoporous organosilica (PMO) with ethane- and phenylene-bridging groups were prepared using 1,2-bis(triethoxysilyl)ethane (BTEE) and 1,4-bis(triethoxysilyl)benzene


Occultation of X-rays from Scorpius X-1 by small trans-neptunian objects
The discovery of such occultation events at millisecond timescales in the X-ray light curve of Scorpius X-1 is reported, in line with an extrapolation of the distribution of sizes of larger TNOs.
Kuiper Belt Object Sizes and Distances from Occultation Observations
There are several observational campaigns underway to detect kilometer-sized foreground Kuiper belt objects (KBOs) through their occultation of background stars. The interpretation of an occultation
Kuiper Belt Objects: Relics from the Accretion Disk of the Sun
▪ Abstract The Kuiper Belt consists of a large number of small, solid bodies in heliocentric orbit beyond Neptune. Discovered as recently as 1992, the Kuiper Belt objects (KBOs) are thought to hold
Can ‘invisible’ bodies be observed in the Solar System?
MANY theories of the origin of comets predict that there are ∼ 1011 comets in the Solar System; most of them, unfortunately, at such a distance that they can never be observed. Some theories go even
▪ Abstract Earth-based stellar occultations probe the temperature, pressure, and number-density profiles of planetary atmospheres in the microbar range with a vertical resolution of a few kilometers.
The Size Distribution of Kuiper Belt Objects
We describe analytical and numerical collisional evolution calculations for the size distribution of icy bodies in the Kuiper belt. For a wide range of bulk properties, initial masses, and orbital
