Solar and stellar flares and their connection [PDF]

This thesis focuses on bridging the gap between solar and stellar physics through the study of flares. Solar flares are the most powerful explosions in the solar system and many stellar flares have been observed to be orders of magnitudes larger ...

The Relationships among Solar Flare Impulsiveness, Energy Release, and Ribbon Development

The Astrophysical Journal
We develop the impulsiveness index, a new classification system for solar flares using the Solar Dynamics Observatory/Extreme Ultraviolet Experiment 304 Å Sun-as-a-star light curves.

Flare Heating in Stellar Coronae

The Astrophysical Journal, 2002
We investigate the contribution of very weak flares to the coronal luminosity of low-mass active stars. We analyze EUVE/DS events data from FK Aqr, V1054 Oph, and AD Leo and conclude that in all these cases the coronal emission is dominated by flares to such an extent that in some cases the entire emission may be ascribed to flare heating.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Effect of stellar flares on the upper atmospheres of HD 189733b and HD 209458b [PDF]

, 2017
Stellar flares are a frequent occurrence on young low-mass stars around which many detected exoplanets orbit. Flares are energetic, impulsive events, and their impact on exoplanetary atmospheres needs to be taken into account when interpreting transit ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

EFTE-SOAR: Two Giant M Dwarf Flares with Rapid Spectroscopic Follow-up

The Astronomical Journal
We present time-series optical spectroscopy of two stellar flares with complex multi-peaked light curves: a $2.{1}_{-.3}^{+.4}\times 1{0}^{34}$ erg flare from an M8 ultra-cool dwarf, and a $1.{5}_{-.2}^{+.2}\times 1{0}^{35}$ erg superflare from an M4 ...

Stellar Flares: Observations and Theory [PDF]

International Astronomical Union Colloquium, 1989
AbstractPhotometric and spectroscopic observations of a very large flare on AD Leo are presented. A self consistent model of a flare corona, transition region and chromosphere is developed; in particular the chromospheric temperature distributions resulting from X-ray and EUV irradiation by coronae of various temperatures are determined.
