N1 - Funding Information: This work was supported by the KESPRINT collaboration, an international consortium devoted to the characterization and research of exoplanets discovered with space-based missions ( http://www.kesprint.science ). This paper includes data collected by the TESS mission. Funding for the TESS mission is provided by the NASA Explorer Program. We acknowledge the use of public TOI Release data from pipelines at the TESS Science Office and at the TESS Science Processing Operations Center. Resources supporting this work were provided by the NASA High-End Computing (HEC) Program through the NASA Advanced Supercomputing (NAS) Division at Ames Research Center for the production of the SPOC data products. This research has made use of the Exoplanet Follow-up Observation Program (Exo-FOP; DOI: 10.26134/ExoFOP5 ) website, which is operated by the California Institute of Technology, under contract with the National Aeronautics and Space Administration under the Exoplanet Exploration Program. This work has made use of data from the European Space Agency (ESA) mission Gaia ( https://www.cosmos.esa.int/Gaia ), processed by the Gaia Data Processing and Analysis Consortium (DPAC, https://www.cosmos.esa.int/web/Gaia/dpac/consortium ). Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement. Based on observations made with the Italian Telescopio Nazionale Galileo (TNG) operated on the island of La Palma by the Fundación Galileo Galilei of the INAF (Instituto Nazionale di Astrofisica) at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias under programmes CAT19A_162, CAT21A_119, CAT22A_111 and ITP19_1. CARMENES is an instrument for the Centro Astronómico Hispano-Alemán de Calar Alto (CAHA, Almería, Spain). CARMENES is funded by the German Max-Planck-Gesellschaft (MPG), the Spanish Consejo Superior de Investigaciones Científicas (CSIC), the European Union through FEDER/ERF FICTS-2011-02 funds, and the members of the CARMENES Consortium (Max-Planck-Institut für Astronomie, Instituto de Astrofísica de Andalucía, Landessternwarte Königstuhl, Institut de Ciències de l’Espai, Institut für Astrophysik Göttingen, Universidad Complutense de Madrid, Thüringer Landessternwarte Tautenburg, Instituto de Astrofísica de Canarias, Hamburger Sternwarte, Centro de Astrobiología and Centro Astronómico Hispano-Alemán), with additional contributions by the Spanish Ministry of Economy, the German Science Foundation through the Major Research Instrumentation Programme and DFG Research Unit FOR2544 “Blue Planets around Red Stars”, the Klaus Tschira Stiftung, the states of Baden-Württemberg and Niedersachsen, and by the Junta de Andalucía. This article is partly based on observations made with the MuSCAT2 instrument, developed by ABC, at the Telescopio Carlos Sánchez operated on the island of Tenerife by the IAC in the Spanish Observatorio del Teide. This work makes use of observations from the LCOGT network. Part of the LCOGT telescope time was granted by NOIRLab through the Mid-Scale Innovations Program (MSIP). MSIP is funded by NSF.

N2 - TOI-1416 is a late G or early K-type dwarf star. TESS detected transits of a planet, TOI-1416 b, around it with a period of 1.07 days. The planet's mass is approximately 3.48 M•, and its radius is about 1.62 R•, resulting in a density slightly less than Earth's. There might be another planet, "c", but it's uncertain due to interference related to the Moon's period. TOI-1416 b is a hot super-Earth-like planet with a temperature of roughly 1570 K. Its composition might be like molten magma with dissolved water, making its atmosphere potentially interesting for transmission spectroscopy using JWST. This planet doesn't fall into a unique category but suggests that planets like it, with ultra-short periods, fall in a broad range up to about 30 days. These are differentiated from other types by the "Neptune Desert" and a valley distinguishing super-Earths from sub-Neptune planets. A pattern has emerged with many small, short-period planets between 0.6-1.4 days. The Neptune Desert's parameters need adjustment due to the discovery of more short-period planets. The defined lower limit of this desert is a radius of 1.6 R• and a mass of 0.028 Mjup. Limits against the planets' insolation and effective temperatures are also provided.
