Context. J1407 (1SWASP J140747.93-394542.6 in full) is a young star in the Scorpius-Centaurus OB association that underwent a series of complex eclipses over 56 days in 2007. To explain these, it was hypothesised that a secondary substellar companion, J1407b, has a giant ring system filling a large fraction of the Hill sphere, causing the eclipses. Observations have not successfully detected J1407b, but do rule out circular orbits for the companion around the primary star. Aims. We test to…

A search for transiting companions in the J1407 (V1400 Cen) system
Context. In 2007, the young star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a complex series of deep eclipses over 56 days. This was attributed to the transit of a ring system filling a large
Constraining the nature of the possible extrasolar PDS110b ring system
The young star PDS110 in the Ori OB1a association underwent two similar eclipses in 2008 and 2011, each of which lasted for a period of at least 25 days. One plausible explanation for these events is
A Self-Gravitating Exoring Around J1407b and Implications for In-Situ Exomoon Formation
We perform simulations of the M ⊕ self-gravitating exoring thought to orbit the large exoplanet J1407b. We use a mass of M J 1407 b = 20 M J (which is close to the revised upper limit) and a
The structure and stability of extended, inclined circumplanetary disc or ring systems
Large dips in the brightness for a number of stars have been observed, for which the tentative explanation is occultation of the star by a transiting circumplanetary disk or ring system. In order for
Constraining the period of the ringed secondary companion to the young star J1407 with photographic plates
Context. The 16 Myr old star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a series of complex eclipses in May 2007, interpreted as the transit of a giant Hill sphere filling debris ring system

With the use of numerical models, we investigate whether Mean Motion Resonances (MMR) with nearby moons to the J1407b ring system were the cause of the observed 0.0267AU wide gap located at 0.4AU.
New Mass and Orbital constraints of J1407b
Objective: The main objective of this research study is to combine the constraints from the value of impact parameter, transit, direct imaging and the radial velocity data to yield the final

In our solar system, the presence of rings is exclusive to the gas giants, but is this the case for all planetary systems? In principle, it seems that rocky exoplanets could also have rings, which
ALMA and NACO observations towards the young exoring transit system J1407 (V1400 Cen)
Aims. Our aim was to directly detect the thermal emission of the putative exoring system responsible for the complex deep transits observed in the light curve for the young Sco-Cen star 1SWASP
An Asymmetric Eclipse Seen toward the Pre-main-sequence Binary System V928 Tau
K2 observations of the weak-lined T Tauri binary V928 Tau A+B show the detection of a single, asymmetric eclipse which may be due to a previously unknown substellar companion eclipsing one component

The light curve of 1SWASP J140747.93-394542.6, a $\sim$16 Myr old star in the Sco-Cen OB association, underwent a complex series of deep eclipses that lasted 56 days, centered on April 2007. This

Wasp-17b: An Ultra-Low Density Planet in a Probable Retrograde Orbit
TLDR
It will be important to determine more precisely the current orbital eccentricity by further high-precision radial velocity measurements or by timing the secondary eclipse, both to reduce the uncertainty on the planet's radius and to test tidal-heating models.

Newly formed planets (or brown dwarfs) may possess disks or rings that occupy an appreciable fraction of the planet's Hill sphere and extend beyond the Laplace radius, where the tidal torque from the
Two families of exocomets in the β Pictoris system
TLDR
An analysis of more than 1,000 archival spectra gathered between 2003 and 2011 provides a sample of about 6,000 variable absorption signatures arising from exocomets transiting the disk of the parent star, showing that the evaporating bodies observed for decades in the β Pictoris system are analogous to the comets in the Solar System.
