Abstract:
We have refined the census of stars and brown dwarfs in the Upper Sco
association (∼10Myr, ∼145pc) by
(1) updating the selection of candidate members from our previous
survey to include the high-precision astrometry from the second data
release of Gaia,
(2) obtaining spectra of a few hundred candidate members to measure
their spectral types and verify their youth, and
(3) assessing the membership (largely with Gaia astrometry) of 2020
stars toward Upper Sco that show evidence of youth in this work and
previous studies.
We arrive at a catalog of 1761 objects that are adopted as members of
Upper Sco. The distribution of spectral types among the adopted
members is similar to those in other nearby star-forming regions,
indicating a similar initial mass function. In previous studies, we
have compiled mid-infrared photometry from the Wide-field Infrared
Survey Explorer and the Spitzer Space Telescope for members of Upper
Sco and used those data to identify the stars that show evidence of
circumstellar disks; we present the same analysis for our new catalog
of members. As in earlier work, we find that the fraction of members
with disks increases with lower stellar masses, ranging from ≲10% for
>1M☉ to ∼22% for 0.01-0.3M☉. Finally, we have estimated the
relative ages of Upper Sco and other young associations using their
sequences of low-mass stars in MGRP versus GBP-GRP. This
comparison indicates that Upper Sco is a factor of two younger than
the βPic association (21-24Myr) according to both nonmagnetic and
magnetic evolutionary models.
Description:
Our observations were performed with the 4m Blanco telescope at the
Cerro Tololo Inter-American Observatory (CTIO), the Magellan Baade
telescope at Las Campanas Observatory, the NASA Infrared Telescope
Facility (IRTF), the Bok Reflector at Steward Observatory, and the
Gemini North and South telescopes. Details on observations are
summarized in table 2.

Note (8): The Gaia parallax and proper motion are consistent with
populations as follows:
O/o = Ophiuchus;
U/u = Upper Sco;
S/s = remainder of Sco-Cen;
n = none of those populations. Upper case letters
Upper case letters indicate that both proper motion and parallax
support membership in that population. Lower case letters indicate
that either proper motion or parallax supports membership while
the other parameter is inaccurate, unreliable, or unavailable.

bl = photometry may be affected by blending with a nearby star;
ext = photometry is known or suspected to be contaminated by
extended emission (no data given when extended emission dominates);

on visual inspection;
off = W3 and/or W4 detection appears offset from the W1/W2 detection
(no data given when offset is due to a known source);
err = W2 magnitudes brighter than ∼6 are erroneous.
