Early Planet Formation in Embedded Disks (eDisk). II. Limited Dust Settling and Prominent Snow Surfaces in the Edge-on Class I Disk IRAS 04302+2247 [PDF]
Astrophysical Journal, 2023 While dust disks around optically visible, Class II protostars are found to be vertically thin, when and how dust settles to the midplane are unclear. As part of the Atacama Large Millimeter/submillimeter Array large program, Early Planet Formation in ...

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

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 ...

A disintegrating minor planet transiting a white dwarf [PDF]
Nature, 2015 Most stars become white dwarfs after they have exhausted their nuclear fuel (the Sun will be one such). Between one-quarter and one-half of white dwarfs have elements heavier than helium in their atmospheres, even though these elements ought to sink ...

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.

MOA-2016-BLG-319Lb: Microlensing Planet Subject to Rare Minor-image Perturbation Degeneracy in Determining Planet Parameters [PDF]
Astronomical Journal, 2018 We present the analysis of the planetary microlensing event MOA-2016-BLG-319. The event light curve is characterized by a brief (∼3 days) anomaly near the peak produced by minor-image perturbations.

(704) Interamnia: a transitional object between a dwarf planet and a typical irregular-shaped minor body [PDF]
Astronomy & Astrophysics, 2019 Context. With an estimated diameter in the 320–350 km range, (704) Interamnia is the fifth largest main belt asteroid and one of the few bodies that fills the gap in size between the four largest bodies with D > 400 km (Ceres, Vesta, Pallas and Hygiea ...

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 ...

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