Published: June 2021

Предложен новый приближенный метод расчета угловых характеристик рассеяния звука на упругих телах неаналитической формы при различных геометрических параметрах стыкуемых фрагментов аналитической формы. Метод базируется на использовании интегральной формулы Кирхгофа и известных строгих решениях задач дифракции звука на упругих аналитических телах. Совместное использование методов динамической теории упругости и разделения переменных с помощью потенциалов Дебая и «типа Дебая» позволяет получить решения задач дифракции звука на изотропных оболочках неаналитической формы, составленных из компонентов сфероидальной, цилиндрической и сферической форм. Вычислены и проанализированы угловые характеристики рассеяния при различных волновых размерах, геометрических и физических параметрах оболочек. Применение рассматриваемого метода имеет особенно актуально в диапазонах низких и средних звуковых частот, где упругие тела являются эффективными рассеивателями звука, что повышает вероятность определения их индивидуальных признаков.
A new approximate method for calculating the angular characteristics of sound scattering on elastic bodies of non-analytical form for various geometric parameters of the joined fragments of the analytical shape we proposed. The method they based on the use of the Kirchhoff integral formula and well-known rigorous solutions of sound diffraction problems on elastic analytical bodies. The combined use of methods of the dynamic theory of elasticity and separation of variables using Debye potentials and "Debye type" potentials allows us to obtain solutions to problems of sound diffraction on isotropic shells of non-analytical form composed of components of spherical, cylindrical and spherical forms. Angular scattering characteristics are calculated and analyzed for various wave sizes, geometric and physical parameters of the shells are calculated. The application of this method is particularly relevant in the low and medium sound frequency ranges, where elastic bodies are effective sound diffusers, which increases the probability of determining their individual characteristics.

Abstract
We present a new ground-based optical transmission spectrum of the ultrahot Jupiter WASP-103b (

K). Our transmission spectrum is the result of combining five new transits from the ACCESS survey and two new transits from the LRG-BEASTS survey with a reanalysis of three archival Gemini/GMOS transits and one VLT/FORS2 transit. Our combined 11-transit transmission spectrum covers a wavelength range of 3900–9450 Å with a median uncertainty in the transit depth of 148 parts per million, which is less than one atmospheric scale height of the planet. In our retrieval analysis of WASP-103b’s combined optical and infrared transmission spectrum, we find strong evidence for unocculted bright regions (4.3σ) and weak evidence for H2O (

), HCN (

), and TiO (

), which could be responsible for WASP-103b’s observed temperature inversion. Our optical transmission spectrum shows significant structure that is in excellent agreement with the extensively studied ultrahot Jupiter WASP-121b, for which the presence of VO has been inferred. For WASP-103b, we find that VO can only provide a reasonable fit to the data if its abundance is implausibly high and we do not account for stellar activity. Our results highlight the precision that can be achieved by ground-based observations and the impacts that stellar activity from F-type stars can have on the interpretation of exoplanet transmission spectra.

Abstract
A line of sight toward the Galactic Center (GC) offers the largest number of potentially habitable systems of any direction in the sky. The Breakthrough Listen program is undertaking the most sensitive and deepest targeted SETI surveys toward the GC. Here, we outline our observing strategies with Robert C. Byrd Green Bank Telescope (GBT) and Parkes telescope to conduct 600 hr of deep observations across 0.7–93 GHz. We report preliminary results from our survey for extraterrestrial intelligence (ETI) beacons across 1–8 GHz with 7.0 and 11.2 hr of observations with Parkes and GBT, respectively. With our narrowband drifting signal search, we were able to place meaningful constraints on ETI transmitters across 1–4 GHz and 3.9–8 GHz with EIRP limits of ≥4 × 1018 W among 60 million stars and ≥5 × 1017 W among half a million stars, respectively. For the first time, we were able to constrain the existence of artificially dispersed transient signals across 3.9–8 GHz with EIRP ≥1 × 1014 W/Hz with a repetition period ≤4.3 hr. We also searched our 11.2 hr of deep observations of the GC and its surrounding region for Fast Radio Burst–like magnetars with the DM up to 5000 pc cm−3 with maximum pulse widths up to 90 ms at 6 GHz. We detected several hundred transient bursts from SGR J1745−2900, but did not detect any new transient bursts with the peak luminosity limit across our observed band of ≥1031 erg s−1 and burst rate of ≥0.23 burst hr−1. These limits are comparable to bright transient emission seen from other Galactic radio-loud magnetars, constraining their presence at the GC.
Collisional Growth and Fragmentation of Dust Aggregates with Low Mass Ratios. I. Critical Collision Velocity for Water Ice

Published: June 2021

Abstract
We investigated fundamental processes of collisional sticking and fragmentation of dust aggregates by carrying out N-body simulations of submicron-sized icy dust monomers. We examined the conditions for collisional growth of two colliding dust aggregates in a wide range of the mass ratio 1–64. We found that the mass transfer from a larger dust aggregate to a smaller one is a dominant process in collisions with a mass ratio of 2–30 and an impact velocity of ≈30–170 m s−1. As a result, the critical velocity, v
fra, for fragmentation of the largest body is considerably reduced for such unequal-mass collisions; v
fra of collisions with a mass ratio of 3 is about half of that obtained from equal-mass collisions. The impact velocity is generally higher for collisions between dust aggregates with higher mass ratios because of the difference between the radial drift velocities in the typical condition of protoplanetary disks (PPDs). Therefore, the reduced v
fra for unequal-mass collisions would delay growth of dust grains in the inner region of PPDs.

We then use all available temperature data within a H ii region to obtain a weighted-average temperature within each ionization zone. We rederive the oxygen abundances of all CHAOS galaxies using this new temperature prioritization method, and we find that the gradients are consistent with the results of a recent study of Berg et al. For NGC 2403, we measure a direct oxygen abundance gradient of −0.09(±0.03) dex/R

Abstract
We analyze six cases of magnetic reconnection with large separatrix angles and separatrix jets observed on the solar disk. The separatrix angle is defined as the angle between the two separatrices on the two sides of the outflow region. The plasma jets are observed immediately downstream of the separatrices. The morphological characteristics and magnetic field configurations of all magnetic reconnections are displayed. At the same time, we calculate several physical parameters of each case, which include the inflow velocity (from 2.3 to 24 km s−1), the outflow velocity (from 1.9 to 43 km s−1), the separatrix jet velocity (from 13 to 82 km s−1), the width (from 0.42 × 103 to 1.2 × 103 km) and length (from 1.4 × 103 to 4.3 × 103 km) of the current sheet, and the separatrix angle θ
sep (from 72° to 128°). We find that the outflow velocity, the separatrix jet velocity, and the width and length of the current sheet are positively related to the inflow velocity, but the separatrix angle does not depend on the inflow velocity and it is related to the initial magnetic field configuration before magnetic reconnection. Meanwhile, the velocities of the outflow and the separatrix jet decrease with increasing

Abstract
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) project has the primary goal of detecting and characterizing low-frequency gravitational waves through high-precision pulsar timing. The mitigation of interstellar effects is crucial to achieve the necessary precision for gravitational wave detection. Effects like dispersion and scattering are stronger at lower observing frequencies, with the variation of these quantities over week–month timescales requiring high-cadence multifrequency observations for pulsar timing projects. In this work, we utilize the dual-frequency observing capability of the Giant Metrewave Radio Telescope (GMRT) and evaluate the potential decrease in dispersion measure (DM) uncertainties when combined with existing pulsar timing array data. We present the timing analysis for four millisecond pulsars observed with the GMRT simultaneously at 322 and 607 MHz, and compare the DM measurements with those obtained through NANOGrav observations with the Green Bank Telescope and Arecibo Observatory at 1400–2300 MHz frequencies. Measured DM values with the GMRT and NANOGrav program show significant offsets for some pulsars, which could be caused by pulse profile evolution between the two frequency bands. In comparison to the predicted DM uncertainties when incorporating these low-frequency data into the NANOGrav data set, we find that higher-precision GMRT data is necessary to provide improved DM measurements. Through the detection and analysis of pulse profile baseline ripple in data on test pulsar B1929+10, we find that, while not important for these data, it may be relevant for other timing data sets. We discuss the possible advantages and challenges of incorporating GMRT data into NANOGrav and International Pulsar Timing Array data sets.

Abstract
During the 24th solar cycle, the Fermi Large Area Telescope (LAT) has observed a total of 27 solar flares possessing delayed γ-ray emission, including the exceptionally well-observed flare and coronal mass ejection (CME) on 2017 September 10. Based on the Fermi/LAT data, we plot, for the first time, maps of possible sources of the delayed >100 MeV γ-ray emission of the 2017 September 10 event. The long-lasting γ-ray emission is localized under the CME core. The γ-ray spectrum exhibits intermittent changes in time, implying that more than one source of high-energy protons was formed during the flare–CME eruption. We find a good statistical correlation between the γ-ray fluences of the Fermi/LAT-observed delayed events and the products of corresponding CME speed and the square root of the soft X-ray flare magnitude. Data support the idea that both flares and CMEs jointly contribute to the production of subrelativistic and relativistic protons near the Sun.

Published: June 2021

Abstract
Tides can have significant effects on the orbital evolution of close-in planets. The evolution of eccentricity and semimajor axis is usually obtained by numerical integration of a set of coupled differential equations. We present here closed-form solutions to the evolution equations and derive from them an expression of the circularization time.
La montée du populisme autoritaire
Authors: Ivaldi Gilles 
Published: June 2021

La revue Futuribles s’intéresse depuis plus de 35 ans à l’évolution des systèmes de valeurs et à l’étude de leur transformation, faisant régulièrement écho aux enquêtes réalisées tous les 9-10 ans dans le cadre de l’ European Values Study . Le dossier ouvert dans ce numéro par Pierre Bréchon porte sur les résultats de la dernière vague (2017-2018) et ce qu’ils nous enseignent concernant les tendances d’évolution des valeurs des Européens sur longue période. Dans ce deuxième article, Gilles Ivaldi s’intéresse à la montée du populisme autoritaire sur le Vieux Continent et à ce que les enquêtes Valeurs nous apprennent sur les facteurs qui l’alimentent au cœur de l’opinion des Européens. Il confronte ici la théorie du cultural backlash développée par Ronald Inglehart et Pippa Norris — selon laquelle ce regain de populisme résulterait d’une contre-révolution culturelle, en réaction à la large diffusion des valeurs libérales — aux évolutions constatées des valeurs des Européens dans les diverses dimensions servant d’indicateurs en la matière (autoritarisme, xénophobie et traditionalisme dans les mœurs). Et comme toujours, la réalité est plus complexe qu’il n’y paraît, entre demande sociale effective d’autorité, recul des valeurs morales traditionnelles, évolution de la xénophobie très différente selon les pays (l’Europe occidentale étant nettement et durablement plus tolérante que l’Europe de l’Est)… Il pointe aussi le processus progressif d’alignement des générations sur une demande accrue de respect de l’autorité. En somme, il convient, lorsqu’on examine la montée des populismes actuellement à l’œuvre, de faire preuve de nuance, en distinguant les aires géographiques, les valeurs concernées (sphère privée vs . sphère publique, par exemple), et en relativisant la dynamique générationnelle. Sans oublier l’impact des facteurs économiques, qui influencent aussi beaucoup les opinions et dont l’auteur souligne, en fin d’article, qu’il pourrait croître dans le contexte actuel de crise — ce que l’enquête Valeurs de 2017 ne peut ici prendre en compte… S.D.
De l’objectif bureaucratique à la naturalité économique
Authors: Demenge Victor 
Published: June 2021

La « croissance économique » occupe une place centrale dans les représentations de l’économie. Cet article établit les conditions de naturalisation de ce chiffre en France et exemplifie ainsi le rôle de l’État dans le désencastrement de l’économie. L’étude porte sur les administrations économiques françaises où la catégorie a été définie et quantifiée. L’enquête conduit à distinguer historiquement la genèse du chiffre de sa naturalisation. Le chiffrage de la croissance est défini après-guerre comme un choix politique destiné à planifier la production. C’est seulement à partir des années 1960 que le chiffre de la croissance devient une « mesure » supposée refléter le plus exactement possible l’état de l’économie. La croissance devient ainsi progressivement une entité indépendante et préexistante à sa quantification. Nous proposons deux explications à ce processus : la transformation de la sociologie des fonctionnaires en charge de la mesurer et les luttes professionnelles qui les opposent. Ces évolutions conduisent à l’élaboration d’instruments de chiffrage faisant de la croissance un phénomène autonome et contraignant.
