We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a M Jup widely separated (∼8″, a = 150 au), young, planetary-mass companion that shares photometric colors and spectroscopic features with the directly ima

ALMA survey of Lupus class III stars: Early planetesimal belt formation and rapid disc dispersal

Autor: Lovell, JB, Wyatt, MC, Ansdell, M, Kama, M, Kennedy, GM, Manara, CF, Marino, S, Matrà, L, Rosotti, G, Tazzari, M, Testi, L, Williams, JP

Class III stars are those in star forming regions without large non-photospheric infrared emission, suggesting recent dispersal of their protoplanetary discs. We observed 30 class III stars in the 1–3 Myr Lupus region with ALMA at ∼856μm, result

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in October 2015, and a sequence of dipping beg

A circumbinary protoplanetary disk in a polar configuration

Autor: Kennedy, GM, Matrà, L, Facchini, S, Milli, J, Panić, O, Price, D, Wilner, DJ, Wyatt, MC, Yelverton, BM

Nearly all young stars are initially surrounded by ‘protoplanetary’ disks of gas and dust, and in the case of single stars at least 30% of these disks go on to form planets1. The process of protoplanetary disk formation can result in initial misa

Detection of Exocometary CO within the 440 Myr Old Fomalhaut Belt: A Similar CO+CO 2 Ice Abundance in Exocomets and Solar System Comets

Recent Atacama Large Millimeter/submillimeter Array observations present mounting evidence for the presence of exocometary gas released within Kuiper Belt analogs around nearby main-sequence stars. This represents a unique opportunity to study their
