Rotational Velocities and Radii Estimates of Low-mass Pre-main-sequence Stars in NGC 2264

open access: yesThe Astrophysical Journal
Investigating the angular momentum evolution of pre-main-sequence (PMS) stars provides important insight into the interactions between Sun-like stars and their protoplanetary disks, and the timescales that govern disk dissipation and planet formation. We

Observational clues to the physics at the magnetosphere in young stellar objects

open access: yesEPJ Web of Conferences, 2014
Classical T Tauri stars offer an excellent laboratory to study the accretion process and star-disk interaction, which define the transfer of mass and angular momentum in the system. The interaction takes place very close to the star, in a region of about

CSI 2264: Accretion process in classical T Tauri stars in the young cluster NGC 2264 [PDF]

open access: yes, 2016
Context. NGC 2264 is a young stellar cluster (~3 Myr) with hundreds of low-mass accreting stars that allow a detailed analysis of the accretion process taking place in the pre-main sequence. Aims.

Magnetospheric accretion on the fully convective classical T Tauri star DN Tau [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
We report here results of spectropolarimetric observations of the classical T Tauri star DN Tau carried out (at 2 epochs) with ESPaDOnS at the Canada-France-Hawaii Telescope within the `Magnetic Protostars and Planets' programme. We infer that DN Tau, with a photospheric temperature of 3,950+-50 K, a luminosity of 0.8+-0.2 Lsun and a rotation period of

Variable X-Ray Emission of the Planet Hosting T Tauri Star CI Tau

open access: yesThe Astronomical Journal
We report results of Chandra X-ray observations of CI Tau, a young magnetically active classical T Tauri star for which previous studies have reported periodic variability attributed to a massive planet in a short-period orbit.

Modeling T Tauri Winds from He I 10830 Profiles [PDF]

open access: yes, 2006
The high opacity of He I 10830 makes it an exceptionally sensitive probe of the inner wind geometry of accreting T Tauri stars. In this line blueshifted absorption below the continuum results from simple scattering of stellar photons, a situation which ...

Ecological Processes Shaping Marine Microbial Assemblages Diverge Between Equatorial and Temperate Time‐Series

open access: yesMolecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Lyα Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems

open access: yesThe Astrophysical Journal, 2023
T Tauri stars produce broad Ly α emission lines that contribute ∼88% of the total UV flux incident on the inner circumstellar disks. Ly α photons are generated at the accretion shocks and in the protostellar chromospheres and must travel through ...
