"Multiple Patchy Cloud Layers in the Planetary-mass Object SIMP 0136+0933" The Astrophysical Journal: an international review of astronomy and astronomical physics, Volume 965, Issue 1, pp.83-83. https://doi.org/10.3847/1538-4357/ad2c760004-637X1538-4357https://hdl.handle.net/2144/48953Multiwavelength photometry of brown dwarfs and planetary-mass objects provides insight into their atmospheres and cloud layers. We present near-simultaneous J- and K_s -band multiwavelength observations of the highly variable T2.5 planetary-mass object, SIMP J013656.5+093347. We reanalyze observations acquired over a single night in 2015 using a recently developed data reduction pipeline. For the first time, we detect a phase shift between J- and K_s -band light curves, which we measure to be 39°.9_-1.1^+3.6. Previously, phase shifts between near-infrared and mid-infrared observations of this object were detected and attributed to probing different depths of the atmosphere, and thus different cloud layers. Using the Sonora Bobcat models, we expand on this idea to show that at least two different patchy cloud layers must be present to explain the measured phase shift. Our results are generally consistent with recent atmospheric retrievals of this object and other similar L/T transition objects.p. 83This article is distributed under the terms of the Creative Commons Attribution 4.0 International.https://creativecommons.org/licenses/by/4.0/Astronomical and space sciencesAtomic, molecular, nuclear, particle and plasma physicsPhysical chemistry (incl. structural)Astronomy & astrophysicsAstronomical sciencesParticle and high energy physicsSpace sciencesArticle2024-04-1510.3847/1538-4357/ad2c760000-0003-2015-5029 (McCarthy, Allison M)0000-0002-0638-8822 (Muirhead, Philip S)0000-0003-2171-5083 (Tamburo, Patrick)0000-0003-0489-1528 (Vos, Johanna M)0000-0002-4404-0456 (Morley, Caroline V)0000-0001-6251-0573 (Faherty, Jacqueline)0000-0001-8170-7072 (Bardalez Gagliuffi, Daniella C)0000-0002-0802-9145 (Agol, Eric)0000-0002-9807-5435 (Theissen, Christopher)915581
