Site selection for the Hayabusa2 artificial cratering and subsurface material sampling on Ryugu
Hayabusa2 took on the challenge of collecting fresh subsurface samples from asteroid (162173) Ryugu during its second touchdown operation. For this ambitious...
Six transiting planets and a chain of Laplace resonances in TOI-178
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are...
Six years of BeppoSAX Wide Field Cameras observations of nine galactic type I X-ray bursters
We present an overview of BeppoSAX Wide Field Cameras observations of the nine most frequent type I X-ray bursters in the Galactic center region. Six years of...
Size and albedo distributions of asteroids in cometary orbits using WISE data
Context. Determining whether asteroids in cometary orbits (ACOs) are dormant or extinct comets is relevant for understanding the end-states of comets and the...
Size Evolution of the Most Massive Galaxies at 1.7 < z < 3 from GOODS NICMOS Survey Imaging
We measure the sizes of 82 massive (M>=1011 Msolar) galaxies at 1.72 our results are compatible with both a leveling off, or a mild evolution in size...
Size of the Accretion Disk in the Graviationally Lensed Quasar SDSS J1004+4112 from the Statistics of Microlensing Magnifications
We present eight monitoring seasons of the four brightest images of the gravitational lens SDSS J1004+4112 observed between 2003 December and 2010 October...
