We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
Understanding the plasma and magnetic field evolution of a filament using observations and Nonlinear force-free field modelling
Stephanie L. Yardley, Antonia Savcheva, Lucie M. Green +4
We present observations and magnetic field models of an intermediate filament present on the Sun in August 2012, associated with a polarity inversion line that extends from AR 1154…
Comprehensive Characterization of Solar Eruptions With Remote and In-Situ Observations, and Modeling: The Major Solar Events on 4 November 2015
Iver H. Cairns, Kamen A. Kozarev, Nariaki V. Nitta +12
Solar energetic particles (SEPs) are an important product of solar activity. They are connected to solar active regions and flares, coronal mass ejections (CMEs), EUV waves, shocks…
Early-Stage SEP Acceleration by CME-Driven Shocks with Realistic Seed Spectra: I. Low corona
Kamen Kozarev, Maher A. Dayeh, Ashraf Farahat
An outstanding problem in heliospheric physics is understanding the acceleration of solar energetic particles (SEP) in coronal mass ejections (CMEs) and flares. A fundamental quest…
The first view of Scuti and Doradus stars with the TESS mission
V. Antoci, M. S. Cunha, D. M. Bowman +63
We present the first asteroseismic results for Scuti and Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample…
XMM-Newton observations of the symbiotic recurrent nova T CrB: evolution of X-ray emission during the active phase
Svetozar A. Zhekov, Toma V. Tomov
We present an analysis of the XMM-Newton observations of the symbiotic recurrent nova T CrB, obtained during its active phase that started in 2015. The XMM-Newton spectra of T CrB…
The beamed jet and quasar core of the distant blazar 4C 71.07
C. M. Raiteri, M. Villata, M. I. Carnerero +5
The object 4C 71.07 is a high-redshift blazar whose spectral energy distribution shows a prominent big blue bump and a strong Compton dominance. We present the results of a two-yea…
Multi-band optical variability of 3C 279 on diverse timescales
Aditi Agarwal, Sergio A. Cellone, Ileana Andruchow +8
We have monitored the flat spectrum radio quasar, 3C 279, in the optical , , and passbands from 2018 February to 2018 July for 24 nights, with a total of 716 frames,…
Population control of Mars Trojans by the Yarkovsky & YORP effects
Apostolos A. Christou, Galin Borisov, Aldo Dell'Oro +3
We explore the hypothesis that the population of Martian Trojans is the result of a balance between the production of new asteroids ("YORPlets") through the YORP effect and their e…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
An eccentric wave in the circumstellar disc of the Be/X-ray binary X Persei
R. K. Zamanov, K. A. Stoyanov, U. Wolter +7
We present spectroscopic observations of the Be/X-ray binary X Per obtained during the period December 2017 - January 2020 (MJD~58095 - MJD~58865). In December 2017 the , ,…
Cosmological Constraints on Chiral Tensor Particles
D. P. Kirilova, E. M. Chizhov
We discuss an extended model with chiral tensor particles in the Universe. Their direct influence on the Universe dynamics and their characteristic interactions in the hot Universe…
