The conditions and evolution of protoplanetary disks in multiple systems can be considerably different from those around single stars, which may have important consequences for planet formation. We present Very Large Array (VLA) 8.8 mm (34 GHz) and 5 cm (6 GHz) observations of the quadruple system HD 98800, which consists of two spectroscopic binary systems (Aa-Ab, Ba-Bb). The Ba-Bb pair is surrounded by a circumbinary disk, which is usually assumed to be a debris disk given its ∼10 Myr age and… 
Long Live the Disk: Lifetimes of Protoplanetary Disks in Hierarchical Triple-star Systems and a Possible Explanation for HD 98800 B
The gas dissipation from a protoplanetary disk is one of the key processes affecting planet formation, and it is widely accepted that it happens on timescales of a few million years for disks around
A circumbinary protoplanetary disk in a polar configuration
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
TIC 278956474: Two Close Binaries in One Young Quadruple System Identified by TESS
We have identified a quadruple system with two close eclipsing binaries in Transiting Exoplanet Survey Satellite (TESS) data. The object is unresolved in Gaia and appears as a single source at

Detection of H2 in the TWA 7 System: A Probable Circumstellar Origin
Using HST–COS far-UV spectra, we have discovered warm molecular hydrogen in the TWA 7 system. TWA 7, a ∼9 Myr old M2.5 star, has a cold debris disk and has previously shown no signs of accretion.
A Coplanar Circumbinary Protoplanetary Disk in the TWA 3 Triple M Dwarf System
We present sensitive ALMA observations of TWA 3, a nearby, young (∼10 Myr) hierarchical system composed of three pre-main-sequence M3–M4.5 stars. For the first time, we detected 12CO and 13CO J = 2–1
The Degree of Alignment between Circumbinary Disks and Their Binary Hosts
All four circumbinary (CB) protoplanetary disks orbiting short-period (P < 20 days) double-lined spectroscopic binaries (SB2s)—a group that includes UZ Tau E, for which we present new Atacama Large

TLDR
Results show that, for a wide range of possible disk properties, a circumbinary disk is far more likely than a narrow ring.
