Searching for signatures of H spicule-like features in the solar transition region
Nived Vilangot Nhalil, Juie Shetye, J. Gerry Doyle
New instrumental and telescopes covering the optical and ultra-violet spectral regions have revealed a range of small-scale dynamic features, many which may be related. For example…
Searching for stellar flares from low mass stars using ASKAP and TESS
Jeremy Rigney, Gavin Ramsay, Eoin P. Carley +7
Solar radio emission at low frequencies (<1 GHz) can provide valuable information on processes driving flares and coronal mass ejections (CMEs). Radio emission has been detected fr…
Detection of spicules termed Rapid Blue-shifted Excursions as seen in the chromosphere via Hα and the transition region via Si iv 1394 Å line emission
Nived Vilangot Nhalil, Juie Shetye, J. Gerry Doyle
We show signatures of spicules termed Rapid Blue-shifted Excursions (RBEs) in the Si iv 1394 Å emission line using a semi-automated detection approach. We use the Hα filtergrams ob…
Doubling of minute-long Quasi-Periodic Pulsations from super-flares on a low mass star
J. Gerry Doyle, Puji Irawati, Dmitrii Y. Kolotkov +5
Using the ULTRASPEC instrument mounted on the 2.4-m Thai National Telescope, we observed two large flares, each with a total energy close to 10^34 erg with sub-second cadence. A co…
The Puzzling Story of Flare Inactive Ultra Fast Rotating M dwarfs. II. Searching for radial velocity variations
Gavin Ramsay, Pasi Hakala, J. Gerry Doyle +2
Observations made using TESS revealed a sample of low mass stars which show a periodic modulation on a period ~d. Surprisingly many of these Ultra Fast Rotating (UFR) stars s…
The Nature of High-frequency Oscillations Associated with Short-lived Spicule-type Events
Juie Shetye, Erwin Verwichte, Marco Stangalini +1
We investigate high resolution spectroscopic and imaging observations from the CRisp Imaging SpectroPolarimeter (CRISP) instrument to study the dynamics of chromospheric spicule ty…
