We crossmatched the exoplanet catalog confirmed before 2021 March 11 with the LAMOST DR7 survey to study their properties. There are 1026 targets with exoplanets observed in the LAMOST DR7 low-resolution spectroscopic survey and 158 targets in the medium-resolution spectroscopic survey. We have calculated the equivalent width of the H{alpha} line and determined their stellar activity. The H{alpha} and flare intensities are almost constant for the Rossby number Ro<=0.12 in the saturated regime and decrease with increasing Ro in the unsaturated regime. In addition, we searched the flare events of all stars with exoplanets in the Transiting Exoplanet Survey Satellite (TESS), Kepler, and K2 surveys. Among the 733 extrasolar planetary systems observed by TESS, we found 481 flares from 57 stars. For Kepler data, we obtained the light curve of 1699 stars and found 1886 flares from 417 stars. For K2 data, we obtained the light curves of 347 stars and found 467 flares from 89 stars. There were light curves of 361 objects with obvious eclipse observed from the TESS survey. We have fitted their light curves with a high signal-to-noise ratio using the JKTEBOP program, and we reobtained the orbital parameters, such as inclination, radius, and period. In the end, we made a judgment on the habitability of exoplanets of stars with flares.2022ApJS..261...26Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/261/26CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)V/156 : LAMOST DR7 catalogs (Luo+, 2019)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/AJ/106/2096 : Limb-darkening coefficients in binaries (Van Hamme 1993)J/AJ/135/785 : SDSS-DR5 low-mass star spectroscopic sample (West+, 2008)J/A+A/505/901 : OGLE-TR-10 u', g' and i'-band photometry (Bentley+, 2009)J/ApJ/707/167 : Transiting planetary system WASP-18 (Southworth+, 2009)J/AJ/140/1402 : M dwarf flares from SDSS spectra (Hilton+, 2010)J/AJ/141/50 : White-light flares on Kepler cool stars (Walkowicz+, 2011)J/ApJ/743/48 : Stars with rot. periods & X-ray luminosities (Wright+, 2011)J/other/Nat/485.478 : Superflares on solar-type stars (Maehara+, 2012)J/ApJS/209/5 : Superflares of Kepler stars.
