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 halo around HD 32297: m-sized cometary dust
Johan Olofsson, Philippe Thébault, Grant M. Kennedy +1
The optical properties of the second generation dust that we observe in debris disks remain quite elusive, whether it is the absorption efficiencies at millimeter wavelengths or th…
Dust production in the debris disk around HR 4796 A
J. Olofsson, J. Milli, P. Thébault +21
Debris disks are the natural by-products of the planet formation process. Scattered or polarized light observations are mostly sensitive to small dust grains that are released from…
Resolving faint structures in the debris disk around TWA7
J. Olofsson, R. G. van Holstein, A. Boccaletti +51
Debris disks are the intrinsic by-products of the star and planet formation processes. Most likely due to instrumental limitations and their natural faintness, little is known abou…
The lithium-rotation connection in the 125 Myr-old Pleiades cluster
J. Bouvier, D. Barrado, E. Moraux +9
The evolution of lithium abundance over a star's lifetime is indicative of transport processes operating in the stellar interior. We revisit the relationship between lithium conten…
Early phases in the stellar and substellar formation and evolution: Infrared and submillimeter data in the Barnard 30 dark cloud
D. Barrado, I. de Gregorio-Monsalvo, N. Huélamo +10
The early evolutionary stage of brown dwarfs are not very well characterized, specially during the embedded phase. To gain insight into the dominant formation mechanism of very low…
Physical parameters of late M-type members of Chamaleon I and TW Hydrae Association: Dust settling, age dispersion and activity
A. Bayo, D. Barrado, F. Allard +6
Although mid-to-late type M dwarfs are the most common stars in our stellar neighborhood, our knowledge of these objects is still limited. Open questions include the evolution of t…
Exocomet signatures around the A-shell star Leo?
C. Eiroa, I. Rebollido, B. Montesinos +18
We present an intensive monitoring of high-resolution spectra of the Ca {\sc ii} K line in the A7IV shell star Leo at very short (minutes, hours), short (night to night), and m…
Near-infrared photometry of WISE J085510.74071442.5
M. R. Zapatero Osorio, N. Lodieu, V. J. S. Béjar +7
(Abridged) We aim at measuring the near-infrared photometry, and deriving the mass, age, temperature, and surface gravity of WISE J085510.74-071442.5 (J0855-0714), which is the coo…
A submillimeter search for pre- and proto-brown dwarfs in Chamaeleon II
I. de Gregorio-Monsalvo, D. Barrado, H. Bouy +7
Context. Chamaeleon II molecular cloud is an active star forming region that offers an excellent opportunity for studying the formation of brown dwarfs in the southern hemisphere.…
