The nearby ultracool dwarf TRAPPIST-1 possesses several Earth-sized terrestrial planets, three of which have equilibrium temperatures that may support liquid surface water, making it a compelling target for exoplanet characterization. TRAPPIST-1 is an active star with frequent flaring, with implications for the habitability of its planets. Superflares (stellar flares whose energy exceeds 10^33 erg) can completely destroy the atmospheres of a cool star's planets, allowing ultraviolet radiation…

Activity and Rotation of Nearby Field M Dwarfs in the TESS Southern Continuous Viewing Zone
The evolution of magnetism in late-type dwarfs remains murky, as we can only weakly predict levels of activity for M dwarfs of a given mass and age. We report results from our spectroscopic survey of
No Such Thing as a Simple Flare: Substructure and Quasi-periodic Pulsations Observed in a Statistical Sample of 20 s Cadence TESS Flares
A 20 s cadence Transiting Exoplanet Survey Satellite monitoring campaign of 226 low-mass flare stars during Cycle 3 recorded 3792 stellar flares of ≥1032 erg. We explore the time-resolved emission
Activity of TRAPPIST–1 analog stars observed with TESS
As more exoplanets are being discovered around ultracool dwarfs, understanding their magnetic activity – and the implications for habitability – is of prime importance. To find stellar flares and
Point spread function estimation for wide field small aperture telescopes with deep neural networks and calibration data
TLDR
The results show that the Tel–Net can successfully reconstruct PSFs of WFSATs of any states and in any positions of the FoV, which is significantly more precise than results obtained by the compared classic method Inverse Distance Weight (IDW) interpolation.
The Deep Neural Network based Photometry Framework for Wide Field Small Aperture Telescopes.
TLDR
The photometry framework proposed in this paper could be used as an end--to--end quick data processing framework for WFSATs, which can further increase response speed and scientific outputs of WFSats.
Evryscope-South Survey of Upper- and Pre-main Sequence Solar Neighborhood Stars
Using photometric data collected by Evryscope-South, we search for nearby young variable systems on the upper main sequence and pre-main sequence. The Evryscopes are all-sky high-cadence telescope
Non-parametric point spread function modelling for adaptive optics systems
TLDR
The recent progress in developing a framework for PSF modelling with non-parametric model is reported and the results show its effectiveness.
Optical and Near-infrared Observations of the Nearby SN Ia 2017cbv
Supernova (SN) 2017cbv in NGC 5643 is one of a handful of type Ia supernovae (SNe~Ia) reported to have excess blue emission at early times. This paper presents extensive $BVRIYJHK_s$-band light

Modeling Repeated M Dwarf Flaring at an Earth-like Planet in the Habitable Zone: Atmospheric Effects for an Unmagnetized Planet
TLDR
The results suggest that active M dwarf hosts may comprehensively destroy ozone shields and subject the surface of magnetically unprotected Earth-like planets to long-term radiation that can damage complex organic structures.
K2 Ultracool Dwarfs Survey. III. White Light Flares Are Ubiquitous in M6-L0 Dwarfs
We report the white light flare rates for 10 ultracool dwarfs (UCDs) using \textit{Kepler K2} short cadence data. Among our sample stars, two have spectral type M6, three are M7, three are M8 and two
The origin of RNA precursors on exoplanets.
TLDR
It is found that the SO32- light chemistry is rapid enough to build up the prebiotic inventory for stars hotter than K5 (4400 K), and how the abiogenesis zone overlaps with the liquid water habitable zone is shown.
UV surface environment of Earth-like planets orbiting FGKM stars through geological evolution
The UV environment of a host star affects the photochemistry in the atmosphere, and ultimately the surface UV environment for terrestrial planets and therefore the conditions for the origin and
Connecting Flares and Transient Mass Loss Events in Magnetically Active Stars
We explore the ramification of associating the energetics of extreme mag- netic reconnection events with transient mass loss in a stellar analogy with solar eruptive events. We establish energy
Frequent Flaring in the TRAPPIST-1 System-Unsuited for Life?
We analyze the K2 light curve of the TRAPPIST-1 system. The Fourier analysis of the data suggests P rot = 3.295 ± 0.003 days. The light curve shows several flares, of which we analyzed 42 events with
