Splitting of Long-period Comet C/2018 F4 (PANSTARRS)

open access: yesThe Astronomical Journal, 2023
Long-period comet C/2018 F4 (PANSTARRS) was observed to show duplicity of its inner region in 2020 September, suggestive of a splitting event. We here present analyses of our observations of the comet taken from the LCO Outbursting Objects Key project ...

1I/`Oumuamua as a Tidal Disruption Fragment From a Binary Star System

open access: yes, 2017
1I/`Oumuamua is the first known interstellar small body, probably being only about 100~m in size. Against expectations based on comets, `Oumuamua does not show any activity and has a very elongated figure, and also exhibits undamped rotational tumbling ...

Near‐Infrared Organic Photovoltaic Electrodes for Subretinal Neurostimulation

open access: yesAdvanced Functional Materials, EarlyView.
Organic photovoltaic electrodes based on the D18:Y6 blend enable precise and light‐controlled activation of retinal ganglion cells in a degenerating retina. NIR Light‐driven activation of retinal ganglion cells, tunable stimulation parameters, and biocompatibility with human retinal organoids highlight their potential for next‐generation prosthetics ...

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

A Candidate Location for Planet Nine from an Interstellar Meteoroid: The Messenger Hypothesis

open access: yesThe Astrophysical Journal, 2023
The existence of a hypothetical Planet Nine lurking in the outer solar system has been invoked as a plausible explanation for the anomalous clustering in the orbits of trans-Neptunian objects.

High-temperature chemical processing on asteroids: An oxygen isotope perspective [PDF]

open access: yes, 2005
From the introduction: Small planetary bodies accreted within 2.4 Myr of solar system formation [1]. The primitive materials (CAIs, chondrules, matrix) incorporated into these asteroids were altered by a variety of secondary processes, including aqueous ...

Poincar\'e surfaces of section around a 3-D irregular body: The case of asteroid 4179 Toutatis

open access: yes, 2017
In general, small bodies of the solar system, e.g., asteroids and comets, have a very irregular shape. This feature affects significantly the gravitational potential around these irregular bodies, which hinders dynamical studies.
