Unresolved Binaries in the Intermediate Mass Range in the Pleiades Star Cluster [PDF]

open access: yesAstronomical Journal, 2022
The identification of binary stars of different mass ratios in resolved stellar populations is a challenging task. We show how the photometric diagram constructed with the pseudocolors (H-W2)-W1 versus W2-(BP-K) can be employed to estimate the binary and

Starspots and Magnetism: Testing the Activity Paradigm in the Pleiades and M67 [PDF]

open access: yes, 2022
We measure starspot filling fractions for 240 stars in the Pleiades and M67 open star clusters using APOGEE high-resolution H-band spectra. For this work we developed a modified spectroscopic pipeline which solves for starspot filling fraction and ...

Reconstructing the Pleiades with Gaia EDR3 [PDF]

open access: yesAstrophysical Journal, 2021
We search through an eight million cubic parsec volume surrounding the Pleiades star cluster and the Sun to identify both the current and past members of the Pleiades cluster within the Gaia EDR3 data set.

Implementing Support Vector Machine Algorithm for Early Slum Identification in Yogyakarta City, Indonesia Using Pleiades Images

open access: yesForum Geografic, 2023
Slums are one of the urban problems that continue to get the attention of the government and the city of Yogyakarta. Over time, cities continue to experience changes in land use due to population growth and migration.

Long-term Spectroscopic Survey of the Pleiades Cluster: The Binary Population [PDF]

open access: yesAstrophysical Journal, 2021
We present the results of a spectroscopic monitoring program of the Pleiades region aimed at completing the census of spectroscopic binaries in the cluster, extending it to longer periods than previously reachable.

Several notes on the elastic properties of mesoporous materials

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023
In this paper, the dependence of the Young’s elastic modulus of a mesoporous material on the geometric characteristics (volume and shape) of pores has been analyzed.

Influence of the initial composition on the phase equilibria in the case of the solid phase separation in binary alloy nanoparticles (exemplifying on the W-Cr system)

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023
Due to a unique set of physico-chemical properties, nanoparticle-fabricated heavy tungsten pseudo-alloys with the ultrafine-grained structure have become an object of a strong interest among researchers in the case of the up-to-date additive powder ...

Glacier-wide seasonal and annual geodetic mass balances from Pléiades stereo images: application to the Glacier d'Argentière, French Alps

open access: yesJournal of Glaciology, 2022
The increased availability of high-resolution and high-quality digital elevation models (DEMs) allows for the investigation of small-scale glaciological changes and improved precision in geodetic mass-balance estimates.

Very High-Resolution Satellite-Derived Bathymetry and Habitat Mapping Using Pleiades-1 and ICESat-2

open access: yesRemote Sensing, 2021
Accurate and reliable bathymetric data are needed for a wide diversity of marine research and management applications. Satellite-derived bathymetry represents a time saving method to map large shallow waters of remote regions compared to the current ...

The one that got away: a unique eclipse in the young brown dwarf Roque 12

open access: yesThe Open Journal of Astrophysics, 2020
We report the discovery of a deep, singular eclipse of the bona fide brown dwarf Roque 12, a substellar member of the Pleiades. The eclipse was 0.6mag deep, lasted 1.3h, and was observed with two telescopes simultaneously in October 2002.
