Photometric and spectroscopic study of 5 pre-main sequence stars in the vicinity of NGC 7129
Evgeni H. Semkov, Sunay I. Ibryamov, Stoyanka P. Peneva
We present results from long-term optical photometric and spectroscopic observations of 5 pre-main sequence stars, located in the vicinity of the bight nebula NGC 7129. We obtained…
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…
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 , ,…
Data-Optimized Coronal Field Model: I. Proof of Concept
K. Dalmasse, A. Savcheva, S. E. Gibson +5
Deriving the strength and direction of the three-dimensional (3D) magnetic field in the solar atmosphere is fundamental for understanding its dynamics. Volume information on the ma…
A study of Variability of the Marginal Am star HD 176843 observed in the Kepler field
C. Ulusoy, I. Stateva, B. Ulaş +4
We present results of a study of the variability of the marginal Am star HD\,176843 observed in the {\it Kepler} field. {\it Kepler} photometry and ground-based spectroscopy are us…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
