SUMMARY:The multi-wavelength effects of stellar activity and the need for 
 a public forecast - Lalitha Sairam (Birmingham)
DTSTART:20221108T130000Z

CONTACT:Dr Jessica Rigley
DESCRIPTION:Contemplating the existence of worlds outside our solar system
  has always intrigued human interest. Since the discovery of the first exo
 planet around the main- sequence star ~25 years ago\, exoplanets have beco
 me the most coveted objects in the Galaxy. Stellar noise produced by magne
 tic activity such as flares\, star spots\, and plages mimics a low- mass e
 xoplanet and creates spurious detections of atmospheric species. Although 
 they are modelled for hindrance\, stellar activity continues to affect det
 ections by reducing the signal. In this talk\, I will give an overview of 
 the challenges that stellar activity poses for exoplanet detection and atm
 ospheric characterisation. I will describe our ongoing project STellar ACt
 vity foreCAst for Optimal observations of exoplanets (STACCATO)\, which is
  a forecasting model to predict the optimal time for exoplanet detection a
 nd atmospheric characteristics reducing the need for stellar activity miti
 gation. I will also demonstrate how this project is synergistic with ongoi
 ng and upcoming missions such as HARPS3\, ARIEL and PLATO.
