Potato-shaped planet discovered about 1.8k light years from solar system

Astronomers have finally announced that an exoplanet discovered a few years ago is a bit like a potato. The planet, called WASP-103b, is located in the constellation Hercules, about 1,800 light-years away from the solar system.

According to Agence France-Presse, WASP-103b is so close to its star, WASP-103, that it is about 50 times farther from the sun than the earth is, so that the cycle of the planet takes only 22 hours, while the cycle of the earth takes 365 days .

Astronomers first discovered the unusually shaped planet in 2014.

“WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral times,” said a study published in the journal Astronomy and Astrophysics.

Measuring the planet’s tidal deformation will allow it to estimate secondary fluid Love numbers and gain insight into WASP-103’s internal structure, the study added. The Love number is a dimensionless parameter that measures the stiffness of a planetary body, and studies have shown that WASP-103b is similar to Jupiter.

“This would allow confinement of the internal structure and composition of WASP-103b, which could provide clues to the expansion of hot Jupiters,” it added.

Suzanne Barros, an astrophysicist at the University of Porto in Portugal, pointed out that if the planet was 1.5 times the mass of Jupiter, its radius would be twice that of Jupiter. Barros predicts that WASP-103b will become very puffy due to the heat of its star, among other mechanisms.

AFP further reported that scientists hypothesized that WASP-103b had a solid core, covered with a layer of liquid, and surrounded by a gaseous atmosphere — just like Jupiter.

Meanwhile, the study, published in Astronomy and Astrophysics, says that future observations with the James Webb Space Telescope could better constrain WASP-103b’s radial Love number because of their high signal-to-noise Infrared limb dimming features smaller than and smaller.

Patterns of behaviour that emerge after trauma

Patterns of behaviour that emerge after trauma

Trauma is a deeply distressing or disturbing experience that can leave a lasting impact on a person’s mental and emotional health. It can result from a range of events, such as natural disasters, accidents, physical or emotional abuse, or military combat. Trauma can have a significant effect on a person’s behavior and can manifest in various ways. Here are some patterns of behavior that often emerge after trauma:

  1. Hyperarousal: After experiencing trauma, a person may feel constantly on edge, with heightened levels of anxiety and tension. This can manifest as irritability, restlessness, and difficulty sleeping.
  2. Avoidance: Trauma can also cause a person to avoid situations, people, or places that remind them of the traumatic experience. This can lead to social withdrawal, isolation, and a loss of interest in previously enjoyable activities.
  3. Emotional numbness: Trauma can cause a person to feel emotionally disconnected or numb, making it difficult for them to experience positive emotions such as joy or love.
  4. Hypervigilance: A person who has experienced trauma may be hyper-aware of their surroundings and perceive threats where none exist. This can lead to an increased sense of danger, which can trigger anxiety or panic attacks.
  5. Flashbacks: Trauma can cause a person to experience vivid and intrusive memories of the traumatic event. These flashbacks can be triggered by a range of stimuli, such as sights, sounds, or smells.
  6. Guilt and shame: Trauma can cause a person to experience feelings of guilt, shame, and self-blame. They may feel responsible for what happened to them, even when it was beyond their control.
  7. Substance abuse: Trauma can lead to the use of drugs or alcohol as a way of coping with difficult emotions. This can quickly become a self-destructive pattern of behavior that exacerbates the trauma.

It’s important to note that not everyone who experiences trauma will display all of these behaviors, and that each person’s response to trauma is unique. However, recognizing these patterns of behavior can help individuals and their loved ones identify when trauma may be a contributing factor to mental and emotional health challenges. Seeking professional support, such as therapy or counseling, can help individuals process their trauma and learn healthy coping mechanisms to manage their behavior.
