Cassini-Plasma Interaction Simulations Revealing the Cassini Ion Wake Characteristics: Implications for In-Situ Data Analyses and Ion Temperature Estimates
Wilson, R. J.; Morooka, M. W.; Hadid, L. Z. +7 more
We have used Spacecraft Plasma Interaction Software (SPIS) simulations to study the characteristics (i.e., dimensions, ion depletion, and evolution with the changing spacecraft attitude) of the Cassini ion wake. We focus on two regions, the plasma disk at 4.5-4.7 RS, where the most prominent wake structure will be formed, and at 7.6 R
Minimally Modified Gravity Fitting Planck Data Better Than ΛCDM
Pookkillath, M. C.
Here we present cosmology of a class of Minimally Modified Gravity theory dubbed as $f(H)$ theory. After introducing a concrete model for the free function, we find that this cosmological model fits Planck data better than $Λ $CDM.
Fundamental properties of stars from Kepler and Gaia data: parallax offset and revised scaling relations
Örtel, S.; Yıldız, M.
Data from the space missions Gaia, Kepler, CoRoT and TESS, make it possible to compare parallax and asteroseismic distances. From the ratio of two densities ρsca/ρπ, we obtain an empirical relation fΔν between the asteroseismic large frequency separation and mean density, which is important for more accurate stella…
Nonsequential neural network for simultaneous, consistent classification, and photometric redshifts of OTELO galaxies
Cepa, J.; Pérez García, A. M.; Alfaro, E. J. +17 more
Context. Computational techniques are essential for mining large databases produced in modern surveys with value-added products.
Aims: This paper presents a machine learning procedure to carry out a galaxy morphological classification and photometric redshift estimates simultaneously. Currently, only a spectral energy distribution (SED) fitti…
Comprehensive list of semi-detached double-lined eclipsing binaries with Gaia DR2 data
Malkov, O. Yu.
Semi-detached eclipsing systems play an important role in our understanding of stellar properties. In the present study, we have cross-matched a previously compiled comprehensive list of SD double-lined eclipsing binaries, containing 119 systems, with Gaia DR2, and analyze the result. A special analysis is conducted for systems with controversial …
Selected phenomena that affect the structure of the cometary landscape
Wesołowski, M.
The paper discusses four processes that may be responsible for shaping the relief of the comet landscape. The considerations take into account the following phenomena: intense sublimation of cometary ice, emission of dust from the surface comet and through jets, migration of dust on the cometary surface, and destruction of fragment the nucleus sur…
Absolute parameters of the W UMa binaries CSS J223614+311343, V523 Aur and V783 And
Michel, Raul; Kjurkchieva, Diana; Popov, Velimir A. +3 more
Photometric BVRc observations of the stars CSS J223614+311343, V523 Aur and V783 And were carried out and their absolute parameters (masses, radii and luminosities) were determined based on light curve modeling and Gaia distances. The main results are: (i) The components of CSS J223614+311343 and V783 And are of K spectral type while th…
Evidence for local particle acceleration in the first recurrent galactic cosmic ray depression observed by Solar Orbiter. The ion event on 19 June 2020
Fedorov, A.; Kulkarni, S. R.; Lario, D. +61 more
Context. In mid-June 2020, the Solar Orbiter (SolO) mission reached its first perihelion at 0.51 au and started its cruise phase, with most of the in situ instruments operating continuously.
Aims: We present the in situ particle measurements of the first proton event observed after the first perihelion obtained by the Energetic Particle Detec…
Using Observations of Solar Vector Magnetic Field from Dual View Points to Remove the 180∘ Ambiguity
Liu, Rui; Zhou, Ru-yun; Wang, Yu-ming +3 more
With Solar Orbiter (SO) being put into successful operational observation, solar magnetic observation has entered the era of remote sensing from dual view points. In this paper, we carried out a simulation of correcting the 180∘ ambiguity of transverse magnetic field with magnetograms from dual view points using an analytical formula as…
