Refinement of Stellar Parameters for the Eclipsing Binary System KIC 8569819 using Stellar Modeling Approach
Dinesha Dharmathilaka, Janaka Adassuriya, Chandana Jayaratne +1
Eclipsing binary systems with a Delta () Scuti component serve a vital role in deriving precise fundamental stellar parameters and testing stellar evolution models. This study m…
Determination of Speed and Source Height of Coronal Shock Waves Using Type II Solar Radio Bursts
G. L. S. S. Liyanage, J. Adassuriya, K. P. S. C. Jayaratne +1
This study examines the shock speed and source height of coronal shock waves using Type II solar radio bursts. The solar radio burst data from January 2022 to October 2023 were obt…
Light Curve Modeling of Eclipsing Binary Systems with Delta Scuti Component
J. A. D. M. Dharmathilaka, J. Adassuriya, K. P. S. C. Jayaratne +1
Astroseismology in eclipsing binaries with Delta () Scuti components offers a powerful means to derive stellar parameters and probe internal structures. To enable accurate frequ…
Curve of Growth Analysis of SZ Lyn
Janaka Adassuriya, Shashikiran Ganesh, Peter de Cat +2
We present one high-resolution and a time series of 561 low-resolution follow-up spectroscopic observations of SZ Lyn. It is a high-amplitude Delta Scuti-type pulsating star in a b…
Spectroscopic observations of novae V1065 CEN and V1280 SCO using 45 cm cassegrain telescope at Arthur C Clarke Institute
S. Gunasekera, J. Adassuriya, I. Madagangoda +2
The spectroscopic observations of two novae namely V1065 CEN and V1280 SCO were made by 45 cm Cassegrain telescope in high resolution (=22000) at H (6563 Å) region. V1065…
Observation of Solar Radio Bursts Using E-CallistoSystem
J Adassuriya, S Gunasekera, KPSC Jayaratne +1
A CALLISTO system was set up at the Arthur C Clarke Institute and connected to the e-CALLISTO global network which observes the solar radio bursts in 24 hours. CALLISTO is the fore…
The Effect of Uniform and Non-uniform Electron Density Models for Determining Shock Speed of a Type II Solar Radio Burst
D P S Nilagarathne, J Adassuriya, H O Wijewardane
Solar flare is one of the most important solar activities which emit all electromagnetic waves in gigantic burst. The radio emission can be used to determine the physical propertie…
Asteroseismology of sz lyn using multi-band high time resolution photometry from ground and space
J. Adassuriya, S. Ganesh, J. L. Gutierrez +4
We report the analysis of high temporal resolution ground and space based photometric observations of SZ Lyncis, a binary star one of whose components is a high amplitude Scuti…
