    • Accretion kinematics through the warped transition disk in hd142527 from resolved CO(6-5) observations 
      Casassus Montero, Simón; Marino Estay, Sebastián; Pérez, S.; Román, P.; Dunhill, A.; Armitage, P. J.; Cuadra, J.; Wootten, A.; Van der Plas, Gerrit; Cieza, L.; Moral, Víctor; Christiaens, V.; Montesinos, Matías (IOP Publishing, 2015)
      The finding of residual gas in the large central cavity of the HD 142527 disk motivates questions regarding the origin of its non-Keplerian kinematics and possible connections with planet formation. We aim to understand ...
    • Cavity and other radial substructures in the disk around HD 97048 
      Van Der Plas, G.; Wright, C. M.; Ménard, F.; Casassus Montero, Simón; Cánovas, H.; Pinte, C.; Maddison, S. T.; Maaskant, K.; Avenhaus, H.; Cieza, L.; Pérez, S.; Ubach, C. (EDP Sciences, 2017)
      Context. Gaps, cavities, and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with a flared disk harbor a cavity, and ...
    • Co gas inside the protoplanetary disk cavity in HD142527: disk structure from ALMA 
      Pérez, S.; Casassus Montero, Simón; Ménard, Francois; Román, P.; Van der Plas, Gerrit; Cieza, L.; Pinte, Christophe; Christiaens, V.; Hales, A. (IOP Pub, 2015)
      Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD142527 hosts a massive protoplanetary disk with a large cavity that extends up to 140 AU from the ...
    • Dust entrainment in photoevaporative winds: densities and imaging 
      Franz, R.; Ercolano, B.; Casassus Montero, Simón Pablo; Picogna, G.; Birnstiel, T.; Pérez, S.; Rab, Ch; Sharma, A. (EDP Sciences, 2022)
      Context. X-ray- and extreme-ultraviolet- (together: XEUV-) driven photoevaporative winds acting on protoplanetary disks around young T-Tauri stars may crucially impact disk evolution, affecting both gas and dust ...
    • Infectious haemolytic anaemia causes jaundice outbreaks in seawater-cultured coho salmon, Oncorhynchus ... 
      Smith Schuster, Pedro; Larenas Herrera, Julio; Contreras Vásquez, Jorge; Cassigoli, J.; Venegas, C.; Rojas, M.E.; Guajardo Vidal, Álvaro; Pérez, S.; Díaz, S. (Blackwell Publishing Ltd, 2006-07-13)
      In the last 9 years, epizootics of an icterus condition has affected coho salmon, Oncorhynchus kisutch (Walbaum), reared in seawater cages in southern regions of Chile. At necropsy, fish from field cases exhibited signs ...
    • Molecular gas in supernova local environments unveiled by EDGE 
      Galbany, Lluis; Mora, L.; González Gaitán, S.; Bolatto, A.; Dannerbauer, H.; López Sánchez, R.; Maeda, K.; Pérez, S.; Pérez Torres, A.; Sánchez, S. F.; Wong, T.; Badenes, C.; Blitz, L.; Marino, R. A.; Utomo, D.; Van de Ven, G. (Oxford University, 2017)
      CO observations allow estimations of the gas content of molecular clouds, which trace thereservoir of cold gas fuelling star formation, as well as to determine extinction via H2col-umn density, N(H2). Here, we studied ...
    • Shadows cast by a warp in the HD 142527 protoplanetary disk 
      Marino, S.; Pérez, S.; Casassus Montero, Simón (IOP Publisihing, 2015)
      Detailed observations of gaps in protoplanetary disks have revealed structures that drive current research on circumstellar disks. One such feature is the two intensity nulls seen along the outer disk of the HD 142527 ...
    • The Circumstellar Disk and Asymmetric Outflow of the EX Lup Outburst System 
      Hales, A. S.; Pérez, S.; Saito, M.; Pinte, C.; Knee, L. B. G.; De Gregorio Monsalvo, Itziar; Dent, B.; López, C.; Plunkett, A.; Cortés, P.; Corder, S.; Cieza, L. (Institute of Physics Publishing, 2018)
      We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0farcs3 resolution of EX Lup, the prototype of the EXor class of outbursting pre-main-sequence stars. The circumstellar disk of EX Lup is ...
    • The morphology of CS Cha circumbinary disk suggesting the existence of a saturn-mass planet 
      Kurtovic, N. T.; Pinilla, P.; Penzlin, Anna B. T.; Benisty, Myriam; Pérez Muñoz, Laura María; Ginski, C.; Isella, A.; Kley, W.; Menard, Francois; Pérez, S.; Bayo, A. (EDP Sciences, 2022)
