Abstract:
The early evolutionary stage of brown dwarfs (BDs) is not very well
characterized, especially during the embedded phase. Our goal is to
gain insight into the dominant formation mechanism of very low-mass
objects and BDs.
We have conducted deep observations at 870um obtained with the
LABOCA bolometer at the APEX telescope in order to identify young
submillimeter (submm) sources in the Barnard 30 dark cloud. We have
complemented these data with multi-wavelength observations from the
optical to the far-IR and compiled complete spectral energy
distributions in order to identify the counterparts, characterize the
sources and to assess their membership to the association and stellar
or substellar status based on the available photometric information.
We have identified 34 submm sources and a substantial number of
possible and probable Barnard 30 members within each individual
APEX/LABOCA beam. They can be classified into three distinct groups.
First, 15 of these 34 have a clear optical or IR counterpart to the
submm peak and nine of them are potential proto-BD candidates.
Moreover, a substantial number of them could be multiple systems. A
second group of 13 sources comprises candidate members with
significant infrared excesses located away from the central submm
emission. All of them include BD candidates, some displaying IR
excess, but their association with submm emission is unclear. In
addition, we have found six starless cores and, based on the total
dust mass estimate, three might be pre-substellar (or pre-BDs) cores.
Finally, the complete characterization of our APEX/LABOCA sources,
focusing on those detected at 24 and/or 70um, indicates that in our
sample of 34 submm sources there are, at least: two WTTs, four CTTs,
five young stellar objects, eight proto-BD candidates (with another
three dubious cases), and one very low luminosity objects.
Description:
This work is focused on submm observations obtained with APEX/LABOCA
at 870um. The region mapped by LABOCA was selected based on the
Spitzer nebulosity. To complement the submm data, we have used both
observations obtained by our group and data retrieved from public
archives covering a broad wavelength range.

Note (1): Notes as follows:
a = B30-LB03 and B30-LB04 very close to each other, see Sect. A.1.
b = IRAS 05286+1203, RA=82.8671, Dec=+12.0899, [12]=0.779±0.0779Jy,
[25]=1.91±0.2101Jy, [60]=9.35±1.7765Jy, [100]=70.4e±14.784Jy.
LB30-LB19d has a MIPS 2 flux at 70um of 0.200 Jy, which translate to
L(int)=0.094L☉ (i.e., a VeLLO). Note that within the LABOCA beam
there is a APEX/SABOCA source detected at 350um
(B30-SB08, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
c = B30-LB20 contains a APEX/SABOCA at 350um
(B30-SB09, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
d = There are two APEX/SABOCA sources within the B30-LB22 beam
(B30-SB03 and B30-SB04, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
e = There are two APEX/SABOCA sources within the B30-LB23 beam
(B30-SB05 and B30-SB06, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
f = B30-LB27 contains a APEX/SABOCA at 350um
(B30-SB12, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
g = B30-LB28 contains a APEX/SABOCA at 350um
(B30-SB16, Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H).
h = IRAS 05293+1207, RA=83.0450, Dec=+12.1629, [12]<0.250Jy, [25]< 0.271Jy,
[60]=1.15±0.1725Jy, [100]< 26.6Jy.
i = B30-LB33 and B30-LB34 very close to each other, see Sect. A.1.
j = The MIPS M2 flux probably corresponds to the counterpart identified
as LB25c.
Note (2): The coordinates have an error of approximately 1 arcsec
(pointing rms, but each APEX/LABOCA cell has a 4 arcsec size).
Note (3): The absolute uncertainty in the flux scale is 8%.
Note (4): For point-like sources, the value is equal to S870.
Note (5): derived using the 870um flux densities and assuming a dust temperature
of 15K (Sanchez-Monge et al. 2013MNRAS.432.3288S 2013MNRAS.432.3288S), and a dust (and gas) mass
opacity coefficient of 0.0175cm2/g (obtained by interpolating the tabulated
values of Ossenkopf & Henning (1994, Cat. J/A+A/291/943), see Sect. 3.1).
The uncertainty in the masses due to the dust temperature and opacity law is
estimated to be a factor of 4.
Note (6): Groups as follows:
A1 = detection at 70 and 24um
A2 = detection at 70 and upper limit at 24um
A2* = detection at 70 and upper limit at 24um, extended emission at 24um
B1 = upper limit at 70um and detection at 24um
B2 = upper limit both at 70 and 24um
B2* = upper limit both at 70 and 24um, extended emission at 24um
C1 = no data at 70um and detection at 24um
C2 = no data at 70um and upper limit at 24um
C2* = no data at 70um and upper limit at 24um, extended emission at 24um
Note (7): Tentative classification as follows:
YSO = young stellar object, with a optical and/or near-IR sources within
5 arcsec of APEX/LABOCA central coordinate. Our tentative
interpretation is that most of them are proto-stars or proto-BDs.
Excess = optical and/or near-IR sources with excesses within the APEX/LABOCA
beam but farther than 5 arcsec. The submm source cannot be assigned
unambiguously to any counterpart so its nature remains unknown.
Starless = possible starless core, since there is neither counterparts closer
than 5 arcsec nor an optical/IR source farther away with excess.
Note (8): the letter for the identification and the BD for the substellar
candidates.

at 350um (Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H)
7 = There is a submm source nearby, namely SB04, detected with APEX/SABOCA
at 350um (Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H)
8 = There is a submm source nearby, namely SB03, detected with APEX/SABOCA
at 350um (Huelamo et al. 2017A&A...597A..17H 2017A&A...597A..17H)
Note (2): Codes as follows:
A1 = Detection at 70 and 24um
A2 = detection at 70 and upper limit at 24um
A2* = detection at 70 and upper limit at 24um, extended emission at 24um
B1 = upper limit at 70um and detection at 24um
C1 = no data at 70um and detection at 24um
YSO = Young Stellar Object, with a optical and/or nearIR sources within
5 arcsec of APEX/LABOCA central coordinate. Our tentative
interpretation is that most of them are proto-stars or proto-BDs.
excess = Optical and/or nearIR sources with excesses within the APEX/LABOCA
beam but farther than 5 arcsec. The submm source cannot be assigned
unambiguously to any counterpart so its nature remains unknown.
Objects without detected emission at 24 and/or 70um are not listed here
(B2 and C2).
Note (3): + for membership status updated from Table 7 to Y? based on all the
available data and our analysis.
Note (4): )*: Possible detection at MIPS 24um, but if real, it might be affected
by the inhomogeneous extended emission by the nebulosity.
