Search for the True Parent Body of the Phoenicid Meteor Shower

The Astronomical Journal
In 2024, Ďurišová et al. found that the meteor shower Phoenicids, IAU No. 254, code PHO, can originate in the nuclei of three comets, 46P/Wirtanen, 104P/Kowal 2, and 289P/Blanpain.

The Formation of Jupiter, the Jovian Early Bombardment and the Delivery of Water to the Asteroid Belt: The Case of (4) Vesta

Life, 2014
The asteroid (4) Vesta, parent body of the Howardite-Eucrite-Diogenite meteorites, is one of the first bodies that formed, mostly from volatile-depleted material, in the Solar System. The Dawn mission recently provided evidence that hydrated material was

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Narrow passband imagery of comets [PDF]

, 1981
During an emission-line survey of the Milky Way, Comet West was accidently imaged through four different narrow passbands with a wide-field, image-intensified camera. Three passbands recorded very similar head plus tail structure.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Infrared observations of comets [PDF]

, 1981
Infrared observation are important for deducing a great deal about properties of the cometary dust surrounding the cometary nucleus. All observations in the infrared are limited to long period comets.

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays

Cytoskeleton, EarlyView.
ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

On the origin of comets [PDF]

, 1976
Physico-chemical processes leading to the dynamic formation and physical evolution of comets are reviewed in relationship to the various theories that propose solar origins, protoplanetary origins, planetary origins and interstellar origins.

Comets [PDF]

, 2015
International audienceComets are low-density, kilometer-sized bodies of ices (mostly H2O, CO2, and CO) and dust (silicates, carbon, and organics), which orbit the Sun along elongated orbits.
