ALMA Observations of the Extraordinary Carina Pillars: HH 901/902
  We present Atacama Large Millimeter/Submillimeter Array (ALMA) 1.3 mm
continuum and C$^{18}$O(2$-$1), N$_2$D$^{+}$(3$-$2), $^{13}$CS(5$-$4), and
$^{12}$CO(2$-$1) line sensitive and high angular resolution ($\sim$0.3$''$)
observations of the famous carina pillars and protostellar objects HH 901/902.
Our observations reveal for the first time, the bipolar CO outflows and the
dusty disks (plus envelopes) that are energizing the extended and irradiated HH
objects far from the pillars. We find that the masses of the disks$+$envelopes
are about 0.1 M$_\odot$ and of the bipolar outflows are between 10$^{-3}$ -
10$^{-4}$ M$_\odot$, which suggests that they could be low- or maybe
intermediate- mass protostars. Moreover, we suggest that these young low-mass
stars are likely embedded Class 0/I protostars with high-accretion rates. We
also show the kinematics of the gas in the pillars together with their
respective gas masses (0.1 -- 0.2 M$_\odot$). We estimate that the pillars will
be photo-evaporated in 10$^4$ to 10$^5$ years by the massive and luminous stars
located in the Trumpler 14 cluster. Finally, given the short photo-evaporated
timescales and that the protostars in these pillars are still very embedded, we
suggest that the disks inside of the pillars will be quickly affected by the
radiation of the massive stars, forming proplyds, like those observed in Orion.
