The interstellar object significance scale (Loeb Scale): astronomical classification of interstellar objects

International Journal of Astrobiology
Abstract The Vera C. Rubin Observatory is expected to increase interstellar object (ISO) detections from a few over the past decade to potentially one per few months, demanding a systematic classification scheme. We present the Interstellar Object Significance Scale (IOSS), also known in the literature as the Loeb Scale, a 0–10 ...

From a Different Star: 3I/ATLAS in the Context of the Ōtautahi–Oxford Interstellar Object Population Model

The Astrophysical Journal Letters
The discovery of the third interstellar object (ISO), 3I/ATLAS (“3I”), provides a rare chance to directly observe a small body from another solar system.

Interstellar extinction from photometric surveys: application to four high-latitude areas

Open Astronomy, 2018
Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

VUV and mid‐UV photoabsorption cross sections of thin films of glycine and alanine: Application to their photochemistry in the solar system

Photochemistry and Photobiology, EarlyView.
Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

A Portrait throughout Perihelion of the NH2-rich Interstellar Comet 2I/Borisov

The Planetary Science Journal
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage.

On Our Cosmic (In)significance

Ratio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

Near-perihelion Activity and Composition of 3I/ATLAS from JUICE/MAJIS Observations

The Astrophysical Journal Letters
We present visible-to-infrared (0.5–5.56 μ m) observations of the interstellar comet 3I/ATLAS obtained with the Moons and Jupiter Imaging Spectrometer aboard the Jupiter Icy Moons Explorer spacecraft between 2025 November 2 and 25, shortly after ...

Interstellar Extinction from Large Surveys

Open Astronomy, 2003
Under some assumptions, information on interstellar extinction may be obtained from modern large photometric survey data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys.

Intersex Across the Interstellar: The Andromeda Constellation in Medieval and Early Modern Astronomical and Astrological Treatises

Renaissance Studies, EarlyView.
ABSTRACT This article examines the iconography of the Andromeda constellation as an intersex figure within medieval and early modern astrological traditions. It focuses on the origins of this imagery in the thirteenth‐century astrological writings of Scot and its reappearance nearly three centuries later in Ratdolt's illustrated 1482 edition of Hyginus'

Streams of interstellar objects

Upcoming surveys are likely to discover a new sample of interstellar objects (ISOs) within the Solar System, but questions remain about the origin and distribution of this population within the Galaxy. ISOs are ejected from their host systems with a range of velocities, spreading out into tidal streams.
