Evidence for Water in the Rocky Debris of a Disrupted Extrasolar Minor Planet [PDF]

open access: yesScience, 2013
Remnants of a Water-Bearing World Stars like the Sun end their lives as white dwarfs. Farihi et al. (p. 218) used detailed spectroscopic analysis of a debris-accreting white dwarf, along with knowledge that such systems accrete this debris from remnants ...

Precise farming through end-to-end technologies [PDF]

open access: yesE3S 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.

The dynamical history of the evaporating or disrupted ice giant planet around white dwarf WD J0914+1914 [PDF]

open access: yes, 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 ...

HelioLinC: A Novel Approach to the Minor Planet Linking Problem

open access: yesAstronomical Journal, 2018
We present HelioLinC, a novel approach to the minor planet linking problem. Our heliocentric transformation-and-propagation algorithm clusters tracklets at common epochs, allowing for the efficient identification of tracklets that represent the same ...

Near Infrared Surface Properties of the Two Intrinsically Brightest Minor Planets (90377) Sedna and (90482) Orcus [PDF]

open access: yes, 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 ...

EVIDENCE FOR AN ANHYDROUS CARBONACEOUS EXTRASOLAR MINOR PLANET [PDF]

open access: yes, 2014
Using Keck/HIRES, we report abundances of 11 different elements heavier than helium in the spectrum of Ton 345, a white dwarf that has accreted one of its own minor planets.

Light curve analysis of main belt asteroids 4747, 5255, 11411, 15433, 17866

open access: yesOpen 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]

open access: yes, 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.

Minor Planet Databases

open access: yesOpen Astronomy, 2015
We cast a retrospective look at the mankind’s acquaintance with minor bodies of the Solar System, at the explosive growth in their discoveries resulting from the technological progress, and at gradual understanding of the danger to our very existence ...
