Constraints on the nearby exoplanet Eps Ind Ab from deep near/mid-infrared imaging limits
Viswanath, Gayathri; Janson, Markus; Dahlqvist, Carl-Henrik; Roche, Dominique Petit dit de la; Samland, Matthias; Girard, Julien; Pathak, Prashant; Kasper, Markus; Feng, Fabo; Meyer, Michael; Boehle, Anna; Quanz, Sascha P.; Jones, Hugh R. A.; Absil, Olivier; Brandner, Wolfgang; Maire, Anne-Lise; Siebenmorgen, Ralf; Sterzik, Michael; Pantin, Eric (2021-07-21)The past decade has seen increasing efforts in detecting and characterising exoplanets by high contrast imaging in the near/mid-infrared, which is the optimal wavelength domain for studying old, cold planets. In this work, ... -
Deep z-band observations of the coolest y dwarf
Kopytova, Taisiya G.; Crossfield, Ian J M; Deacon, Niall R.; Brandner, Wolfgang; Buenzli, Esther; Bayo, Amelia; Schlieder, Joshua E.; Manjavacas, Elena; Biller, Beth A.; Kopon, Derek (2014-11-17)WISE J085510.83-071442.5 (hereafter, WISE 0855-07) is the coolest Y dwarf known to date and is located at a distance of 2.31 ± 0.08 pc, giving it the fourth largest parallax of any known star or brown dwarf system. We ... -
Variability in a young, L/T transition planetary-mass object
Biller, Beth A.; Vos, Johanna; Bonavita, Mariangela; Buenzli, Esther; Baxter, Claire; Crossfield, Ian J. M.; Allers, Katelyn; Liu, Michael C.; Bonnefoy, Mickaël; Deacon, Niall; Brandner, Wolfgang; Schlieder, Joshua E.; Dupuy, Trent; Kopytova, Taisiya; Manjavacas, Elena; Allard, France; Homeier, Derek; Henning, Thomas (2015-11-10)As part of our ongoing NTT SoFI survey for variability in young free-floating planets and low-mass brown dwarfs, we detect significant variability in the young, free-floating planetary-mass object PSO J318.5-22, likely due ...
