Explosive events associated with a surge
M. S. Madjarska, J. G. Doyle, B. de Pontieu
The solar atmosphere contains a wide variety of small-scale transient features. Here, we explore the inter-relation between some of them such as surges, explosive events and blinke…
A Mini-survey of Ultracool Dwarfs at 4.9 GHz
A. Antonova, J. G. Doyle, G. Hallinan +2
A selection of ultracool dwarfs are known to be radio active, with both gyrosynchrotron emission and the electron cyclotron maser instability being given as likely emission mechani…
Small-scale flows in SUMER and TRACE high-cadence co-observations
M. S. Madjarska, J. G. Doyle
We report on the physical properties of small-scale transient flows observed simultaneously at high cadence with the SUMER spectrometer and the TRACE imager in the plage area of an…
Jets or high velocity flows revealed in high-cadence spectrometer and imager co-observations?
M. S. Madjarska, J. G. Doyle, D. Innes +1
We report on active region EUV dynamic events observed simultaneously at high-cadence with SUMER/SoHO and TRACE. Although the features appear in the TRACE Fe ix/x 171A images as je…
Rotational Modulation of M/L Dwarfs due to Magnetic Spots
C. Lane, G. Hallinan, R. T. Zavala +7
We find periodic I-band variability in two ultracool dwarfs, TVLM 513-46546 and 2MASS J00361617+1821104, on either side of the M/L dwarf boundary. Both of these targets are short-p…
Sporadic Long-term Variability in Radio Activity from a Brown Dwarf
A. Antonova, J. G. Doyle, G. Hallinan +2
Radio activity has been observed in a large variety of stellar objects, including in the last few years, ultra-cool dwarfs. To explore the extent of long-term radio activity in ult…
