- text: Solar Observations by Angelo Secchi. I. Digitization of Original Documents |
|
|
and Analysis of Group Numbers over the Period of 1853-1878. Angelo Secchi, an |
|
|
Italian Jesuit and prominent scientist of the 19th century, and one of the founders |
|
|
of modern astrophysics, observed the Sun regularly at the Collegio Romano in Rome, |
|
|
Italy, for more than 25 yr. Results from his observations are reported in articles |
|
|
published in the scientific journals of the time, as well as in drawings and personal |
|
|
notebooks that are stored in the historical archive of the Istituto Nazionale |
|
|
di Astrofisica Osservatorio Astronomico di Roma. The latter material, which reports |
|
|
solar observations performed from 1853-1878, includes original documents from |
|
|
Secchi and from a few of his close collaborators. The above unique material has |
|
|
recently been digitized for preservation purposes and for allowing the scientific |
|
|
exploitation of data not easily accessible so far. A total of more than 5400 digital |
|
|
images have been produced. Here we present the archival material and the new digital |
|
|
data derived from it. We also present results obtained from our primary analysis |
|
|
of the new digital data. In particular, we produced new measurements of the group |
|
|
number from 1853-1878, which will be available for future recalibration of the |
|
|
group number series. |

|
|
across its Surface. A multiwavelength regionally dependent photometric analysis |
|
|
of Pluto''s anti-Charon-facing hemisphere using images collected by New Horizons'' |
|
|
Multispectral Visible Imaging Camera (MVIC) reveals large variations in the absolute |
|
|
value and spectral slope of the single-scattering albedo. Four regions of interest |
|
|
are analyzed: the dark equatorial belt, Pluto''s north pole, nitrogen-rich regions, |
|
|
and the mid-latitude terrains. Regions dominated by volatile ices such as Lowell |
|
|
Regio and Sputnik Planitia present single-scattering albedos of ∼0.98 at 492 nm, |
|
|
almost neutral across MVIC''s visible wavelength range (400-910 nm), indicating |
|
|
limited contributions from tholin materials. Pluto''s dark equatorial regions, |
|
|
informally named Cthulhu and Krun Maculae, have single-scattering albedos of ∼0.16 |
|
|
at 492 nm and are the reddest regions. Applying the Hapke radiative transfer model |
|
|
to combined MVIC and Linear Etalon Imaging Spectral Array (LEISA) spectra (400-2500 |
|
|
nm) of Cthulhu Macula and Lowell Regio successfully reproduces the spectral properties |
|
|
of these two regions of dramatically disparate coloration, composition, and morphology. |
|
|
Since this model uses only a single coloring agent, very similar to the Titan-like |
|
|
tholin of Khare et al., to account for all of Pluto''s colors, this result supports |
|
|
the Grundy et al. conclusion that Pluto''s coloration is the result of photochemical |
|
|
products mostly produced in the atmosphere. Although cosmic rays and extreme ultraviolet |
|
|
photons reach Pluto''s surface where they can drive chemical processing, observations |
|
|
of diverse surface colors do not require different chemical products produced |
|
|
in different environments. We report a correction scaling factor in the LEISA |
|
|
radiometric calibration of 0.74 ± 0.05.' |

# KAILAS |
|
|
KAILAS (aka Keyword Labeler At SciX aka Indus-UAT-Labeler aka nasa-smd-ibm-v0.1_UAT_Labeler) is a RoBERTa-based, Encoder-only transformer model, domain-adapted for NASA Science Mission Directorate (SMD) applications. It's fine-tuned on scientific journals and articles relevant to NASA SMD, aiming to enhance natural language technologies like information retrieval and intelligent search. |
|
|
This specific fork was finetuned on SciX Digital Library (https://scixplorer.org/, formerly NASA-ADS) proprietary data to label text with UAT labels (https://astrothesaurus.org/) |
