ALMA uncovers highly filamentary structure towards the Sgr E region
J. Wallace, C. Battersby, E. A. C. Mills +7
We report on the discovery of linear filaments observed in CO(1-0) emission for a field of view toward the Sgr E star forming region centered at (l,b)=(358.720, 0.…
HATS-74Ab, HATS-75b, HATS-76b and HATS-77b: Four Transiting Giant Planets around K and M Dwarfs
A. Jordán, J. D. Hartman, D. Bayliss +32
The relative rarity of giant planets around low mass stars compared with solar-type stars is a key prediction from core accretion planet formation theory. In this paper we report o…
HATS-37Ab and HATS-38b: Two Transiting Hot Neptunes in the Desert
A. Jordán, G. Á. Bakos, D. Bayliss +24
We report the discovery of two transiting Neptunes by the HATSouth survey. The planet HATS-37Ab has a mass of 0.099 +- 0.042 M_J (31.5 +- 13.4 M_earth) and a radius of 0.606 +- 0.0…
A Search for Transiting Planets in the Globular Cluster M4 with K2: Candidates and Occurrence Limits
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos
We perform a search for transiting planets in the NASA K2 observations of the globular cluster (GC) M4. This search is sensitive to larger orbital periods ( days, com…
A Search for Variable Stars in the Globular Cluster M4 with K2
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos +1
We extract light curves for 4554 objects with in the K2 superstamp observations of the globular cluster M4, including 3784 cluster members, and search for variability. Amo…
Ultralow-amplitude RR Lyrae Stars in M4
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos +1
We report evidence for a new class of variable star, which we dub millimagnitude RR Lyrae (mmRR). From K2 observations of the globular cluster M4, we find that out of 24 horizontal…
Collisional Fragmentation is Not a Barrier to Close-in Planet Formation
Joshua Wallace, Scott Tremaine, John Chambers
Collisional fragmentation is shown to not be a barrier to rocky planet formation at small distances from the host star. Simple analytic arguments demonstrate that rocky planet form…
Detecting the Supernova Breakout Burst in Terrestrial Neutrino Detectors
Joshua Wallace, Adam Burrows, Joshua C. Dolence
We calculate the distance-dependent performance of a few representative terrestrial neutrino detectors in detecting and measuring the properties of the breakout burst light c…
Anisotropic Lyman-alpha Emission
Zheng Zheng, Joshua Wallace
As a result of resonant scatterings off hydrogen atoms, Lyman-alpha (Lya) emission from star-forming galaxies provides a probe of the (hardly isotropic) neutral gas environment aro…
