The Sizes of the Nearest Young Stars

  title={The Sizes of the Nearest Young Stars},
  author={Kyle McCarthy and Russel J. White},
  journal={The Astronomical Journal},
We present moderate resolution (R ~ 3575) optical spectra of 19 known or suspected members of the AB Doradus and ? Pictoris Moving Groups, obtained with the DeVeny Spectrograph on the 72 inch Perkins telescope at Lowell Observatory. For four of five recently proposed members, signatures of youth such as Li I 6708 ? absorption and H? emission further strengthen the case for youth and membership. The lack of detected lithium in the proposed ? Pic member TYC?2211-1309-1 implies that it is older…

Search for associations containing young stars (SACY). VII. New stellar and substellar candidate members in the young associations
Context. The young associations offer us one of the best opportunities to study the properties of young stellar and substellar objects and to directly image planets thanks to their proximity (<200
AB Dor Moving Group Stars Resolved with the CHARA Array
We present interferometric measurements obtained with the CHARA Array of 13 adolescent-age stars in nearby moving groups. The motivation was to spatially resolve the largest stars and to search for
Young, active radio stars in the AB Doradus moving group
Context. Precise determination of stellar masses is necessary to test the validity of pre-main-sequence (PMS) stellar evolutionary models, whose predictions are in disagreement with measurements for
Searching for new young stars in the Northern hemisphere: the Pisces moving group
Using the kinematically unbiased technique described in Binks, Jeffries & Maxted (2015), we present optical spectra for a further 122 rapidly-rotating (rotation periods < 6 days), X-ray active FGK
BANYAN. XII. New Members of Nearby Young Associations from GAIA–Tycho Data
We present a search for stellar members of young associations within 150 pc of the Sun based on Gaia-Tycho and an updated version of the BANYAN $\Sigma$ software to determine Bayesian membership
The β Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
Aims. We intended to compile the most complete catalog of bona fide members and candidate members of the β Pictoris association, and to measure their rotation periods and basic properties from our
Intrinsic Colors, Temperatures, and Bolometric Corrections of Pre-Main Sequence Stars
We present an analysis of the intrinsic colors and temperatures of 5-30 Myr old pre-main sequence (pre-MS) stars using the F0 through M9 type members of nearby, negligibly reddened groups: η Cha
Is multiplicity universal? : a study of multiplicity in the young moving groups
The young moving groups are collections of nearby (<200 pc), young (5-150 Myr) premain sequence stars; these stars offer us one of the best opportunities to characterise stellar multiplicity,
On the age of the β Pictoris moving group
Jeffries & Binks (2014) and Malo et al. (2014) have recently reported Li depletion boundary (LDB) ages for the {\beta} Pictoris moving group (BPMG) which are twice as old as the oft-cited kinematic
Planets around Low-mass Stars (PALMS). VI. Discovery of a Remarkably Red Planetary-mass Companion to the AB Dor Moving Group Candidate 2MASS J22362452+4751425*
We report the discovery of an extremely red planetary-mass companion to 2MASS J22362452+4751425, a ≈0.6 M⊙ late-K dwarf likely belonging to the ~120 Myr AB Doradus moving group. 2M2236+4751 b was


Search for associations containing young stars (SACY) - III. Ages and Li abundances
Context. Our study is a follow-up of the SACY project, an extended high spectral resolution survey of more than two thousand optical counterparts of X-ray sources in the Southern Hemisphere targeted
We present results from our continuing program to identify new, low-mass, members of the nearby young moving groups (NYMGs) using a proper motion selection algorithm and various observational
Nearby Young Stars Selected by Proper Motion. I. Four New Members of the β Pictoris Moving Group From The Tycho-2 Catalog
We describe a procedure to identify stars from nearby moving groups and associations out of catalogs of stars with large proper motions. We show that from the mean motion vector of a known or

We present a new census of the stellar and substellar members of the young cluster IC 348. We have obtained images at I and Z for a 42' × 28' field encompassing the cluster and have combined these
