TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit
A. Alqasim, N. Grieves, N. M. Rosário +129
We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…
HD 21520 b: a warm sub-Neptune transiting a bright G dwarf
Molly Nies, Ismael Mireles, François Bouchy +49
We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, K, $R_{\star} = 1.04\pm 0.02…
TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b
Stephanie Yoshida, Shreyas Vissapragada, David W. Latham +51
We present the discovery of TOI-1420b, an exceptionally low-density ( g cm) transiting planet in a day orbit around a late G dwarf star. Using tra…
A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842
Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske +32
We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial veloci…
TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
Fei Dai, Kento Masuda, Corey Beard +60
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMR). Dynamical evolution over time could…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
TOI-1296b and TOI-1298b observed with TESS and SOPHIE: Two hot Saturn-mass exoplanets with different densities around metal-rich stars
C. Moutou, J. M. Almenara, G. Hébrard +40
We present the discovery of two new transiting extrasolar planet candidates identified as TOI-1296.01 and TOI-1298.01 by the Transiting Exoplanet Survey Satellite (TESS). The plane…
The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert
S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
PTFO 8-8695: Two Stars, Two Signals, No Planet
L. G. Bouma, J. N. Winn, G. R. Ricker +13
PTFO 8-8695 (CVSO 30) is a star in the 7-10 million year old Orion-OB1a cluster that shows brightness dips that resemble planetary transits. Although strong evidence against the pl…
X-ray Flashes or soft Gamma-ray Bursts? The case of the likely distant XRF 040912
G. Stratta, S. Basa, N. Butler +49
In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. We performed a detailed spectral and temp…
HETE-2 Localization and Observations of the Gamma-Ray Burst GRB 020813
R. Sato, the HETE Science Team
A bright, long gamma-ray burst (GRB) was detected and localized by the instruments on board the High Energy Transient Explorer 2 satellite (HETE-2) at 02:44:19.17 UTC (9859.17 s UT…
Discovery of the short gamma-ray burst GRB 050709
J. S. Villasenor, D. Q. Lamb, G. R. Ricker +30
Gamma-Ray Bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in…
HETE-2 Localization and Observation of the Bright, X-Ray-Rich Gamma-Ray Burst GRB021211
G. B. Crew, D. Q. Lamb, G. R. Ricker +35
A bright, x-ray-rich GRB was detected by HETE-2 at 11:18:34.03 UT on 11 Dec 2002. The WXM localization was to 14' and relayed to the GCN 22 s after the start of the burst. The grou…
