Maureira, María José; Arce, Héctor G.; Offner, Stella S. R.; Dunham, Michael M.; Pineda, Jaime E.; Fernández López, Manuel; Chen, Xuepeng; Mardones Pérez, Diego (IOP Publishing Ltd., 2017)We use CARMA 3 mm continuum and molecular lines (NH2D, N2H+, HCO+, HCN, and CS) at similar to 1000 au resolution to characterize the structure and kinematics of the envelope surrounding the deeply embedded first core ...

ALMA cycle 1 observations of the hh46/47 molecular outflow: structure, entrainment, and core impact Zhang, Yichen; Arce, Héctor G.; Mardones Pérez, Diego; Cabrit, Sylvie; Dunham, Michael M.; Garay Brignardello, Guido; Noriega-Crespo, Alberto; Offner, Stella; Raga, Alejandro; Corder, Stuartt A. (The American Astronomical Society, 2016-12-01)We present Atacama Large Millimeter/sub-millimeter Array Cycle 1 observations of the HH 46/47 molecular outflow using combined 12 m array and Atacama Compact Array observations. The improved angular resolution and sensitivity ...

Maureira, María José; Arce, Héctor G.; Dunham, Michael M.; Mardones Pérez, Diego; Guzmán, Andrés E.; Pineda, Jaime E.; Bourke, Tyler L. (Oxford University Press, 2020)We present ALMA3 mm molecular line and continuum observations with a resolution of similar to 3.5 arcsec towards five first hydrostatic core (FHSC) candidates (L1451-mm, Per-bolo 58, Per-bolo 45, L1448-IRS2E, and Cha-MMS1). ...

Arce, Héctor G.; Mardones Pérez, Diego; Corder, Stuartt A.; Garay Brignardello, Guido; Noriega - Crespo, Alberto; Raga, Alejandro C. (The American Astronomical Society, 2013-09-01)The morphology, kinematics, and entrainment mechanism of the HH 46/47 molecular outflow were studied using new ALMA Cycle 0 observations. Results show that the blue and red lobes are strikingly different. We argue that ...

Plunkett, Adele L.; Arce, Héctor G.; Corder, Stuartt A.; Dunham, Michael M.; Garay Brignardello, Guido; Mardones Pérez, Diego (The American Astronomical Society., 2015-04-10)Molecular outflows driven by protostellar cluster members likely impact their surroundings and contribute to turbulence, affecting subsequent star formation. The very young Serpens South cluster consists of a particularly high ...

Plunkett, Adele; Fernández López, Manuel; Arce, Héctor; Busquet, Gemma; Vivanco Mardones, Diego; Dunham, Michael (EDP Sciences, 2018-07-03)Context. Clusters are common sites of star formation, whose members display varying degrees of mass segregation. The cause may be primordial or dynamical, or a combination both. If mass segregation were to be observed in ...

Maureira, María José; Arce, Héctor G.; Dunham, Michael M.; Pineda, Jaime E.; Fernández-López, Manuel; Chen, Xuepeng; Mardones Pérez, Diego (IOP Publishing, 2017)We use 3 mm multiline and continuum CARMA observations toward the first hydrostatic core (FHSC) candidate L1451-mm to characterize the envelope kinematics at 1000 au scales and investigate its evolutionary state. We detect ...
