Structure of the zodiacal cloud: new analytical and numerical solutions [PDF]

open access: yesEarth, Planets and Space, 2014
Recent results of analytical and numerical modelling of the interplanetary dust (IPD) distribution are described. They have been obtained with a new techniques employing the continuity equation written in the space of orbital coordinates. A 3-D structure and the corresponding 2-D slices for the IPD cloud governed by the Poynting-Robertson drag are ...

Art as a Channel and Embodiment of Symbolic Interaction Between Migrants and Non‐Migrants

open access: yesSymbolic Interaction, Volume 48, Issue 3, Page 410-440, August 2025.
Many non‐migrant politicians, journalists, and scholars in migrant‐destination societies often represent migrants with self‐interested objectives and in specific instrumental ways based on stereotypes. Yet research on symbolic interaction reveals migrants are not passive victims.

1.3.3 Consequences of the Inclination of the Zodiacal Cloud on the Ecliptic [PDF]

open access: yesInternational Astronomical Union Colloquium, 1976
Assuming that the decrease in the density of the interplanetary dust follows an exponential distribution both in the transverse and radial direction, we can write n = no Exp(-(h/H)-(r-l/R)), where h is the distance from the ecliptic plane and r the heliocentric distance both expressed in astronomical units (a.u.); then we show that the modulation of ...

A Rotational Disruption Crisis for Zodiacal Dust

open access: yesThe Astrophysical Journal Letters
A systematic torque from anisotropic radiation can rapidly spin up irregular grains to the point of breakup. We apply the standard theory of rotational disruption from radiative torques to solar system grains, finding that grains with radii ∼0.03–3 μ m ...

Camera‐traps and the city: Spatiotemporal adaptations of wildlife to urban environments

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Urbanisation may deeply alter wildlife behaviour and predator–prey dynamics by driving spatiotemporal adaptations to human activity and environmental features. Year‐round camera‐trap surveys in Firenze, Central Italy, revealed increased nocturnality, strong predator–prey temporal overlap at night and biodiversity patterns shaped by artificial light ...

Application of Nonspherical Dust Models to Polarization of Zodiacal Light Observed with DIRBE/COBE

open access: yesThe Astrophysical Journal
The composition, size, and shape of interplanetary dust (IPD) grains record their origin and are inferred from in situ counts and remote sensing of scattered sunlight and thermal emission.

Catherine Hutton's Travel Diary (1779)

open access: yesJournal for Eighteenth-Century Studies, Volume 48, Issue 1, Page 47-70, March 2025.
Abstract The only diary the author Catherine Hutton (1756–1846) is known to have kept is her travel diary, written in 1779 at the age of 23, in which she describes staying with various members of her extended family and friends while travelling around the Midlands.

Understanding the Dust Environment at Mercury: From Surface to Exosphere

open access: yesThe Planetary Science Journal
We provide an overview of our understanding of the dust environment at Mercury and the role that dust plays in shaping the planet's surface and exosphere.

Preimpact Detection of Chelyabinsk‐Type Objects in the Thermal Infrared: Possibilities and Limitations

open access: yesAdvances in Astronomy, Volume 2025, Issue 1, 2025.
The Chelyabinsk meteor entered Earth’s atmosphere on 15 February 2013, producing a shock wave that injured about 1500 people and damaged thousands of buildings. Despite its relatively large size (∼20 m), the progenitor asteroid approached Earth undetected. Its apparent radiant was too close to the Sun for standard ground‐based near‐Earth asteroid (NEA)

Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of α Centauri A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits

open access: yesThe Astrophysical Journal Letters
We report on coronagraphic observations of the nearest solar-type star, α Centauri A ( α Cen A), using the MIRI instrument on the James Webb Space Telescope.
