IEEE Access, 2018 Compared with conventional drill, an ultrasonic drill can break into rocks under lower weight on bit and lower power, which is more suitable to sample in low gravity environment for deep-space exploration. However, the ultrasonic drill cannot remove rock

Detectability of the Yarkovsky Effect in the Main Belt
The Planetary Science Journal, 2023 We attempt to detect a signal of Yarkovsky-related acceleration in the orbits of 134 main belt asteroids (MBAs) we observed with the University of Hawai’i 88 inch telescope, supplemented with observations publicly available from the Minor Planet Center ...

The unexpected narrowness of eccentric debris rings: a sign of eccentricity during the protoplanetary disc phase [PDF]
Royal Society Open Science, 2020 This paper shows that the eccentric debris rings seen around the stars Fomalhaut and HD 202628 are narrower than expected in the standard eccentric planet perturbation scenario (sometimes referred to as ‘pericentre glow’). The standard scenario posits an

Constraining planet formation around 6M⊙-8M⊙ stars [PDF]
, 2020 Identifying planets around O-type and B-type stars is inherently difficult; the most massive known planet host has a mass of only about 3M⊙. However, planetary systems which survive the transformation of their host stars into white dwarfs can be detected

Precise farming through end-to-end technologies [PDF]
E3S Web of Conferences, 2023 New times require new approaches to be implemented in different sectors, as old methods are irrelevant. New challenges such as overpopulation and its branches of events that are negatively affecting our planet and likewise humans and other living things.

Near Infrared Surface Properties of the Two Intrinsically Brightest Minor Planets (90377) Sedna and (90482) Orcus [PDF]
, 2005 We present low resolution K band spectra taken at the Gemini 8 meter telescope of (90377) Sedna and (90482) Orcus (provisional designations 2003 VB12 and 2004 DW, respectively), currently the two minor planets with the greatest absolute magnitudes (i.e ...

Viscous avalanches on a spherical minor planet [PDF]
EPJ Web of ConferencesGranular avalanches influence the surface evolution of small celestial bodies such as asteroids and moons. Understanding their dynamics is crucial for interpreting surface features observed by space missions. We adapt a depth-averaged shallow water model

Light curve analysis of main belt asteroids 4747, 5255, 11411, 15433, 17866
Open Astronomy, 2023 The main belt asteroids 4747, 5255, 11411, 15433, and 17866 were studied at the Baldone Astrophysical Observatory in the time span range 2018–2022. The obtained light curve data together with published Minor Planet Center data are analyzed with Fourier ...

Ten New and Updated Multi-planet Systems, and a Survey of Exoplanetary Systems [PDF]
, 2009 We present the latest velocities for 10 multi-planet systems, including a re-analysis of archival Keck and Lick data, resulting in improved velocities that supersede our previously published measurements.
