Minor planet astrophotometry [PDF]
, 2012 Historically, the Minor Planet Center (MPC) has concentrated on improving the quality of the astrometric observations and the resulting orbits of minor planets. In light of long-standing complaints in the literature about the quality of the photometric parameters for the minor planets, there has been a need to improve the quality of the absolute ...

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

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 ...

Two drastically different climate states on an Earth-like terra-planet [PDF]
Earth System Dynamics, 2018 We study an Earth-like terra-planet (water-limited terrestrial planet) with an overland recycling mechanism bringing fresh water back from the high latitudes to the low latitudes.

Minor Planet 2008 ED69 and the Kappa Cygnid Meteor Shower [PDF]
, 2008 Until recently, the kappa Cygnids (IAU#12) were considered an old shower, because the meteors were significantly dispersed in node, radiant, and speed, despite being 28-38° inclined.

The dynamical history of the evaporating or disrupted ice giant planet around white dwarf WD J0914+1914 [PDF]
, 2020 Robust evidence of an ice giant planet shedding its atmosphere around the white dwarf WD J0914+1914 represents a milestone in exoplanetary science, allowing us to finally supplement our knowledge of white dwarf metal pollution, debris discs and minor ...

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
