The circumstellar environment of the young, low-mass dipper star JH 223. Accretion and large-scale magnetic field topology
T. P. Freitas, J. Bouvier, B. Zaire +11
Studies of magnetospheric accretion and magnetic field topology in T Tauri stars have advanced over the years, but their applications to fully convective, very-low-mass T Tauri sta…
The optical photometric variability of Herbig Ae/Be stars from TESS
Ann Marie Cody, Lynne A. Hillenbrand, Shreya Chandragiri +1
We have carried out a photometric time domain study of 188 intermediate-mass young stars observed in Full Frame Image mode with the TESS satellite over the first 3.3 years of its m…
A Search for Transiting Exocomets in TESS Sectors 1-26
Azib Norazman, Grant M. Kennedy, Ann Marie Cody +3
We present a search for single photometric exocomet transits using a magnitude-limited sample of stars observed by the TESS primary mission. These events are asymmetric, with a sha…
Do accretion-powered stellar winds help spin down T Tauri stars?
Lukas Gehrig, Eric Gaidos, Laura Venuti +2
How T Tauri stars remain slowly rotating while still accreting material is a long-standing puzzle. Current models suggest that these stars may lose angular momentum through magneto…
