Covertly Active Comet (139359) 2001 ME1

The Planetary Science Journal
On 2018 November 18, coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) captured an unrecognized comet crossing its fields of view. We identified this comet to be the minor planet (139359) 2001 ME _1 , whose previously unnoticed dust ...

Dynamics of long period comets [PDF]

, 1987
The appearance of Halley's Comet in 1985 to 1986 and the related emphasis on research on physical models of cometary nuclei, led to a more moderate pace for the dynamical studies of the Oort cloud and the motion of long-period comets this year.

Long-period comets with non-gravitational effects

, 2004
The influence of non-gravitational effects on the motion of long-period comets is analyzed. Investigations were performed for about 60 nearly-parabolic comets discovered during the last thirty years. All three non-gravitational parameters $A_{\rm{1}}, A_{

Experimental Sleep Restriction Blunts Positive Emotions and Aesthetic Experiences When Viewing Artwork

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep loss influences basic emotional and cognitive processes, but its impact on higher‐order naturalistic cognition, such as aesthetic judgements, is less understood. The current study primarily investigated whether experimental sleep restriction altered aesthetic evaluations of abstract artwork, and secondarily tested whether these ...

Gelato: A Mission Concept for Comet Surface Sample Return

The Planetary Science Journal
Understanding the role of comets in solar system formation and evolution has continued to be a driving question in planetary science. It is believed that comets host a record of presolar history and early planet formation and likely delivered volatiles ...

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.

Definition and recommendations for trial methods for evaluating dentin hypersensitivity: A hybrid AI‐assisted scoping review and Delphi consensus process

Periodontology 2000, EarlyView.
Abstract Background Dentin hypersensitivity (DH) is a common yet inconsistently defined condition impacting oral health and quality of life. Variability in diagnostic criteria and trial methodologies has limited comparability of previous research. Objectives To map current definitions, diagnostic frameworks, and clinical trial methodologies in DH ...

Are Trojan collisional families a source for short--period comets?

, 1995
We have investigated the dynamical evolution of fragments generated by the impact breakup of Trojan asteroids, in order to study the formation of collisional families in the Trojan clouds and to identify a possible genetic connection between these ...

Origins of Solar Systems Workshop: The Origin, Evolution, and Detectability of Short Period Comets [PDF]

, 1993
The origin of the short period comets (SPC) (periods less than 200 years), the dynamical formation of their present reservoir(s), the cause and rate of their transport to the inner planetary region where they can be detected, and the magnitude of ...
