Revisiting the HD 21749 Planetary System with Stellar Activity Modeling

Tianjun Gan, Sharon Xuesong Wang, Johanna K. Teske +26

HD 21749 is a bright ( mag) K dwarf at 16 pc known to host an inner terrestrial planet HD 21749c as well as an outer sub-Neptune HD 21749b, both delivered by TESS. Follow-up…

Two young planetary systems around field stars with ages between 20-320 Myr from TESS

George Zhou, Samuel N. Quinn, Jonathan Irwin +46

Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages Myr from observa…

Orbital Foregrounds for Ultra-Short Duration Transients

Hank Corbett, Nicholas M. Law, Alan Vasquez Soto +7

Reflections from objects in Earth orbit can produce sub-second, star-like optical flashes similar to astrophysical transients. Reflections have historically caused false alarms for…

The Magellan-TESS Survey I: Survey Description and Mid-Survey Results

Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66

revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…

TOI 122b and TOI 237b, two small warm planets orbiting inactive M dwarfs, found by \textit{TESS}

William C. Waalkes, Zachory K. Berta-Thompson, Karen A. Collins +39

We report the discovery and validation of TOI 122b and TOI 237b, two warm planets transiting inactive M dwarfs observed by \textit{TESS}. Our analysis shows TOI 122b has a radius o…

From core collapse to superluminous: The rates of massive stellar explosions from the Palomar Transient Factory

C. Frohmaier, C. R. Angus, M. Vincenzi +8

We present measurements of the local core collapse supernova (SN) rate using SN discoveries from the Palomar Transient Factory (PTF). We use a Monte Carlo simulation of hundreds of…
