Abstract:
We have conducted a novel search of most of the southern sky for nearby
red dwarfs having low proper motions, with specific emphasis on those
with µ<0.18"/yr, the lower cutoff of Luyten's classic proper-motion
catalog. We used a tightly constrained search of the SuperCOSMOS database
and a suite of photometric distance relations for photographic BRI and
2MASS JHKs magnitudes to estimate distances to more than 14 million
red dwarf candidates. Here we discuss 29 stars in 26 systems estimated
to be within 25 pc, all of which have µ<0.18"/yr, that we have
investigated using milliarcsecond astrometry, VRI photometry, and
low-resolution spectroscopy. In total, we present the first parallaxes
of 20 star systems, 9 of which are within 25 pc. We have additionally
identified 14 young M dwarfs, of which 3 are new members of the nearby
young moving groups, and 72 new giants, including two new carbon stars.
We also present the entire catalog of 1215 sources we have identified
by this means.
Description:
In this paper, we present a survey of those very low-proper-motion stars,
along with astrometric, photometric, and spectroscopic follow-up
observations for selected high-priority stars and other additional targets
of interest from the Cerro Tololo Inter-american Observatory Parallax
Investigation (CTIOPI) parallax program.
To create a more detailed picture of the solar neighborhood, we have
carried out a search of the southern sky for stars with tiny proper
motions, less than 0.18"/yr, dubbed TINYMO.
Through the existing CTIOPI program (operating since 1999 on the CTIO
0.9 m; Jao et al. 2005AJ....129.1954J 2005AJ....129.1954J; Henry et al. 2006AJ....132.2360H 2006AJ....132.2360H),
we have obtained Johnson-Kron-Cousins VRI photometry (Jao et al.
2003AJ....125..332J 2003AJ....125..332J; Winters et al. 2015, J/AJ/149/5) for all 187 targets.
Target fields are observed in each filter on photometric nights and then
transformed to Johnson-Kron-Cousins VRI through the use of standards from
Landolt (1992, Cat. II/183; 2007, J/AJ/133/2502). Stars were observed on
at least two nights to check for consistent VRI photometry.

Note (1): The VRI photometry and variability are original, and JHKs is
reprinted from the 2MASS Point Source Catalog (Cutri et al. 2003,
Cat. II/246).
Note (2): Spectral types (given in Table 3) were determined using the MATCHSTAR
code (Riedel et al. 2014, J/AJ/147/85), a template-matching code that operates
by comparing input red-optical spectra to a series of spectral standard-star
spectra (Kirkpatrick et al. 1991ApJS...77..417K 1991ApJS...77..417K; Henry et al.
1994AJ....108.1437H 1994AJ....108.1437H). The code selects the portions of the spectrum held in
common between both target and standard star, masks out the atmospheric bands
and Hα emission line, divides the spectra by the templates, and takes
the lowest standard deviation of a match as the correct spectral type.
Note (3): Note as follows:
J = Indicates joint spectral types from unresolved multiples.

Note (1): Spectral types are derived from comparisons to dwarfs and may not be
accurate.
Note (2): Note as follows:
var = New large-amplitude photometric variable;
e = Indicates that Hα was found in emission in the spectra.
Note (3): Note as follows:
b = Variable status inferred from >1 mag R2 and Rkc magnitude mismatch;
c = Variable status inferred from >1 mag R1 and R2 plate magnitude mismatch;
d = Variable status inferred from >1 mag R1 and Rkc magnitude mismatch;
e = Rkc filter variability 0.18 mag;
f = Rkc filter variability 0.31 mag;

Note (1): We consider LACEwING membership probabilities of 20%-50% to be low,
50%-75% to be medium, and 75%-100% to be high.
Note (2): Youth flag as follows:
h = Hα stronger than -10Å;
N = Low surface gravity by sodium index;
K = Low surface gravity by potassium EW.
In all cases, these stars appears below the curves in Figures 15, 16, and 17.
