    • A turbulent origin for the complex envelope kinematics in the young low-mass core Per - Bolo 58 
      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 ...
    • ALMA observations of envelopes around first hydrostatic core candidates 
      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). ...
    • Distribution of Serpens South protostars revealed with ALMA 
      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 ...
    • Imaging the water snow-line during a protostellar outburst 
      Cieza González, Lucas; Casassus Montero, Simón; Tobin, John; Bos, Steven; Williams, Jonathan; Pérez, Sebastián; Zhu, Zhaohuan; Canovas, Héctor; Dunham, Michael; Hales, Antonio; Prieto, José; Principe, David; Schreiber, Matthias; Ruiz Rodríguez, Dary; Zurlo, Alice (Nature Publishing Group, 2016)
      A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role in disk evolution by promoting the rapid ...
    • Kinematics of a Young Low-mass Star-forming Core: Understanding the Evolutionary State of the First-core ... 
      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 ...
    • The VLA/ALMA nascent disk and multiplicity (VANDAM) survey of Orion protostars. A statistical characterization ... 
      Tobin, John; Sheehan, Patrick; Megeath, S. Thomas; Díaz Rodríguez, Ana; Offner, Stella; Murillo, Nadia; Van 't Hoff, Merel; Van Dishoeck, Ewine; Osorio, Mayra; Anglada, Guillem; Furlan, Elise; Stutz, Amelia; Reynolds, Nickalas; Karnath, Nicole; Fischer, William; Persson, Magnus; Looney, Leslie; Li, Zhi-Yun; Stephens, Ian; Chandler, Claire; Cox, Erin; Dunham, Michael; Tychoniec, Lukasz; Kama, Mihkel; Kratter, Kaitlin; Kounkel, Marina; Mazur, Brian; Maud, Luke; Patel, Lisa; Pérez, Laura; Sadavoy, Sarah; Segura Cox, Dominique; Sharma, Rajeeb; Stephenson, Brian; Watson, Dan; Wyrowski, Friedrich (IOP Publishing, 2020)
      We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very ...
    • The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Perseus Protostars. VI. Characterizing the ... 
      Tobin, John; Looney, Leslie; Li, Zhi; Sadavoy, Sarah; Dunham, Michael; Segura-Cox, Dominique; Kratter, Kaitlin; Chandler, Claire; Melis, Carl; Harris, Robert; Perez, Laura (Institute of Physics Publishing, 2018)
      We present Atacama Large Millimeter/submillimeter Array observations of multiple protostar systems in the Perseus molecular cloud, previously detected by the Karl G. Jansky Very Large Array. We observe 17 close (<600 au ...
