We present a flare star catalog from four years of non-targeted millimeter-wave survey data from the South Pole Telescope (SPT). The data were taken with the SPT-3G camera and cover a 1500-square-degree region of the sky from $20^{h}40^{m}0^{s}$ to $

First Evidence of the Frequency Filtering of Magnetoacoustic Waves in the Flaring Star EK Dra

Autor: Srivastava, A. K., Pandey, J. C., Karmakar, Subhajeet, Chowdhury, Partha, Moon, Y. -J., Goossens, Marcel, Jelínek, P., Mathioudakis, M., Doyle, J. G., Dwivedi, B. N.

Using the data obtained from XMM-Newton, we show the gradual evolution of two periodicities of ~4500 s and ~2200 s in the decay phase of the flare observed in a solar analog EK Dra. The longer period evolves firstly for first 14 ks, while the shorter

The Role of Erupting Sigmoid in Triggering a Flare with Parallel and Large-Scale Quasi-Circular Ribbons

Autor: Joshi, Navin Chandra, Liu, Chang, Sun, Xudong, Wang, Haimin, Magara, Tetsuya, Moon, Y. -J.

In this paper, we present observations and analysis of an interesting sigmoid formation, eruption and the associated flare that occurred on 2014 April 18 using multi-wavelength data sets. We discuss the possible role of the sigmoid eruption in trigge

Influence of graphene-substrate interactions on configurations of organic molecules on graphene: pentacene/epitaxial graphene/SiC

Autor: Jung, W., Oh, D. -H., Song, I., Shin, H. -C., Ahn, S. J., Moon, Y., Park, C. -Y., Ahn, J. R.

Pentacene has been used widely in organic devices, and the interface structure between pentacene and a substrate is known to significantly influence device performances. Here we demonstrate that molecular ordering of pentacene on graphene depends on
